Good teacher. His explanations are easy to understand. Today I am 72 years old and a Happy retired worker. It’s the first time that I have at last understood the basics of Electronics! Thanks to you, professor.🙏
Electronics are really fun and interesting and they are more accessible than ever! I don't know if it's your plan, but spending retirement tinkering with machinery seems like a great idea.
The coolest granny, trust you will study in the heavenly library when you get there. I would love to reach your age and still enjoy studying. I'm a 26 years old young man, have little knowledge, wasted so many years on irrelevant things, but I'm new now and want to spend the rest of my life for knowledge.

This was a very good tutorial. I thought the instructor did a wonderful job walking the viewers through the use of resistors. He had great examples, explained things well with pertinent illustrations. And he had a very good voice for instructing.
Wow what incredible timing! I just got a beginners electronics assembly kit from my girlfriend for Christmas to give me a head start before my engineering classes start soon. This will definitely be helpful
I'm currently asking myself how do you know so much? You are a literal genius, you have hundreds of videos for so many different areas, I don't know how someone can know so much information.
I love the way you explain everything. ive always worked on computers and main boards, but its nice knowing whats going on at the physics level. thanks for the video.
Awesome Electronics Tutorial: V=IR - P=VI - Green LED = 2 Vdc drop across it - total R in series - total R in parallel - Well illustrated Potentiometer explanation i will add that the C terminal is also called the variable WIPER.

Thank god this exists I’m going back to study electrical engineering after 2 years of doing nothing and I have to relearn years of information before august lol
An important point for anyone not understanding the fundamental "what actually *is* voltage/current": A rough concept to consider is how electricity is being transmitted. Electrons loosely speaking are responsible for electricity. A coulomb is a measure of electrical charge. A couloumb represents a number of electrons, regardless of their state. This is charge. The number isn't immediately important. It's a big number. Electrons aren't "consumed"; they have a level of energy at which they've been excited, and transmit this energy to power things. Energy is measured in Joules. The same joules in any other form of measurement of energy, e.g. chemical energy. So if each electron is holding a certain number of joules, and a multitude of electrons make up a coulomb, we can state how much energy is contained in this collection of electrons as the number of Joules per Coulomb. "Joules per coulomb" is the same as "Volts". V = J/C = Joules per Coulomb. Current is the "rate of flow of charge". As previously mentioned, charge is measured in coulombs. It gives the number of coulombs passing a point per in a circuit per second, regardless of how many joules possesed by those coulombs. I = C/s = coulombs per second. So with this in mind, power (Joules per second, measured in Watts), can be found by muliplying the two measurements together. The fractions cancel out: J/C x C/s = J/s = Watts! This explains why voltage goes down across a component, e.g. lightbulb, as Joules are being taken from the electrons/coulombs and are being converted to light!
So the same electron can "carry" a different amount of Joules with it? There must be an interval for the amount of Joules an electron can carry right? How do I find that? And what exactly is the Joules of an electron? Is it its kinetic energy?
@@ElVerdaderoAbejorro Joules of electrons is actually is the energy possessed by then when electric field is applied to them to move in ordered manner rather than random drifting which is without application of external voltage. • Random motion of electrons - Thermal energy. (Joules of Heat) • Ordered motion of electrons - Electrical energy. (Joules of electricity).
@@ElVerdaderoAbejorro 1. There is no such thing like the intervals of energy carrying. As long as these electrons are in motion then either in random or ordered they carries possessed energy at any instant. 2. When there is no external voltage then only the thermal energy they can carry. In this condition if any temperature difference is imposed then heat transfer will takes place in metals. 3. When electric voltage or field is imposed then they moves in ordered fashion as long as there is no resistance in the conducting path they continues to possess the electrical energy. 4. The only one state microscopically exist when these electrons are ceased to motion or motionless I.e. absolute zero Kelvin condition. Then only they don't carry or possess any energy at all. 5. So, there is always some form of energy these electrons possess at any instant of time in the metal or conducting material. There is no any particular interval needs to take into account. But yes, if we want the energy transferred in that period of time (range of instants) then it is V*I*∆t or I^2 *R* ∆t. At every instant, electron is in balanced condition of energy transaction.
This video made me finally have that oh shit I’m an idiot moment, that very moment everything clicks!!! Thank you so much! Seriously thank you, I’ve been staring at my Arduino sensors just with mass confusion!! Resistance was the one thing I couldn’t understand. Finally clicked when you pretty much said, resistance is a gate, we only need 2 people to work, resistance opens the gate for two workers, and shuts it to 1000 people trying to also get in!
Seriously, thank you for taking the time to post these videos. I’m so grateful to live in an age that we can learn anything anywhere because of people like you. Do you have Patreon or something like it? I’d gladly donate.
If you is interested in electronics the greatest results that i've ever had was by using the Gregs Electro Blog (i found it on google) without a doubt the most useful course that I have ever tried.
This man teaches us theory in the most efficient way 🎉🎉❤❤ Meanwhile ElectroBoom teaches the same theory in practical in the most funny and entertaining way 😂😂😂
Remember your video title and audience: Basic Electronics for Beginners. Already, at 0:22 you’re jumping into calculating resistance when you haven’t even touched the basic idea of why a resistor is needed in the first place. Now look at the screen at 4:57. Does that look anywhere near “basic?” At this point, this “beginner” is totally left in the dust. Now go to 21:53. This beginner is frustrated and is thinking of quitting the quest of learning the basics of electronics. Just letting you know that this video is definitely not basic and not for beginners. But it was presented free to me and I thank you for your time.
@@greenbeginner3353 Well, you've to understand...Is it? And if you think you're better...do it on your own and kindly make a playlist...Let us know, what's your method of teaching?? :) Have a nice day... :)
@@tabassam-ali I am trying to learn electronics. I’m looking for basic information for beginners. I saw a video that said it was basic information for beginners but it was not basic and not for beginners. So, I commented accordingly. So, what did I do wrong?
It's so cool explanation innet ? You are teaching better than my electronic teacher when I was studying at technical high school and university. I subscribe your channel.
Thank you for looking up that topic [basic electronic ] for me.“Keep up the great work.”I wanted to express my gratitude for your help and support today.
You can....just give it time....literally everything u know is because u gave it time to sink in and for u to master it... it is well.. God will see us through....I also am learning
For the explanation that starts around 28:21, what happens when both paths have exactly the same resistance? Will it follow both paths? Also, if electrons only flow through the path of least resistance, how do parallel circuits exist?
My hypothesis for the 2nd question was that I misinterpreted you, as I suspected you never said/suggest that electrons only flow through the path of least resistance, but @29:00-29:15 seems to prove me wrong. My next hypothesis is that you just misphrased yourself. After conducting a google search I found that "electricity passes through all possible paths whether the resistance is high or low. Just the difference is that the current is more in which resistance is less." We can dismiss my 2nd question for being based on a false assumption. The result from my google also answers my first question. Under any circumstance, electrons will follow both paths, just in different proportions.
I learnt electronics ages ago, for 45 years didn't use it, watching these videos brought me back to my youth!! Will watch them all and get back to the electronics saddle, as a hobbyist now!! Million thanks for all !!
Love the video thank you!!! 4:35 I can’t lie, for a very brief moment I truly believed half of 100 was and I may have been getting it completely wrong my whole life 😂
As a Navy trained Avionics Technician, I was elated that you explained that current flows from negative to positive. Benjamin Franklin was a great man but he confused generations for years.
I think @20:24 is wrong. The voltage drop of the entire circuit is still 9V, so to find the current in the circuit you'd divide 9V by 10,250 Ohms + resistance of the lightbulb (which we don't know but it should be negligible anyway). Why should the method you explained be correct?
I guess it's because (when we treat the 10k ohm and 350 ohm resistors as one 10.35k ohm resistor) we know the resistor's resistance and its voltage drop, and ohm's law is always valid. Ok maybe I just had a brain fart. I hope I can come back to this later and look back at how dumb I'm being here.
I learned the product-over-sum rule for pairs of parallel resistors. ie R1*R2/(R1 + R2). Sometimes it's easier to work out by hand. It's less nice for 3 or more parallel resistors, but it still works as long as you only do two at a time, and calculated pairs you can think of as its own resistor. For instance: with 3 resistors in parallel, you can do R1,2 = R1*R2/(R1 + R2) and R1,2,3 = R1,2*R3/(R1,2 + R3) With 4 resistors in parallel, you can do R3,4 = R3*R4/(R3 + R4) and R1,2,3,4 = R1,2*R3,4/(R1,2 + R3,4) Etc. Like I used to tell my math students, sometimes it isn't a "more right" way or a "superior" way, just another tool that sometimes is a better fit to your problem.
Amazing Video! ⭐ Question: From time 11:17 -15:01, video inserts 7V in equation solving for resistance. My limited knowledge tells me to insert 9V, not 7V. Why 7V??..... :) Thank you.
No mistake was made. 7 volts because 2 volts are required for the led. Don’t want to resist all 9 volts or the led will have trouble lighting so…(9volts-2volts)=7volts.
In a parrallel circuit, there is a different wat to calculate it if you are not good with fractions. The formula is r1 x r2/r1+r2. If there are multiple resistors then the answer from the first 2 resistors turns into Re. therefor the formal now becomes RexR3/Re + R3 and so on.
Im sitting the GAMSAT on friday 20th Feb. If i get over 70 ill donate $20 to your go fund me. Your videos have helped me more than the $400 course i bought lol
If your looking for a cool comment you're in the wrong place, but if your looking for an outstanding pie recipe you've come to the right place. Ingredients: 1. 6 tablespoons unsalted butter 2. 1/2 cup white sugar 3. 1/2 cup brown sugar 4. 1/4 cup water 5. 1/4 teaspoon cinnamon 6. 1 pinch salt 7. 5 apples - peeled, cored and sliced 8. 1 pastry for double-crust pie Directions: 1. Preheat oven to 425 degrees F (220 degrees C). 2. Combine butter, white sugar, brown sugar, water, cinnamon, and salt in a saucepan over medium heat. Bring to a boil, remove from heat and set aside. 3. Roll out half the pastry to fit a 9-inch pie plate. Place bottom crust in pie plate; pour in apple slices. 4. Roll out top crust into a 10-inch circle. Cut into 8 (1-inch) wide strips with a sharp paring knife or pastry wheel. Weave the pastry strips, one at a time, into a lattice pattern. Fold the ends of the lattice strips under the edge of the bottom crust and crimp to seal. 5. Pour butter-sugar mixture over top of pie, coating the lattice, and allowing any remaining sauce to drizzle through the crust. 6. Bake in the preheated oven for 15 minutes. Reduce heat to 350 degrees F (175 degrees C), and bake until the crust is golden brown, the caramel on the top crust is set, and the apple filling is bubbling, 35 to 40 more minutes. Allow to cool completely before slicing.
Memory effect exists in resistors, too. A 000 smd resistor resists, after several use, it will become fully conductive. Smart batteries have such resistors inside the battery pack.

This video helped me a ton even with my limited algebra knowledge. Thank you!!
If your looking for a cool comment you're in the wrong place, but if your looking for an outstanding pie recipe you've come to the right place.
Ingredients:
1. 6 tablespoons unsalted butter
2. 1/2 cup white sugar
3. 1/2 cup brown sugar
4. 1/4 cup water
5. 1/4 teaspoon cinnamon
6. 1 pinch salt
7. 5 apples - peeled, cored and sliced
8. 1 pastry for double-crust pie
Directions:
1. Preheat oven to 425 degrees F (220 degrees C).
2. Combine butter, white sugar, brown sugar, water, cinnamon, and salt in a saucepan over medium heat. Bring to a boil, remove from heat and set aside.
3. Roll out half the pastry to fit a 9-inch pie plate. Place bottom crust in pie plate; pour in apple slices.
4. Roll out top crust into a 10-inch circle. Cut into 8 (1-inch) wide strips with a sharp paring knife or pastry wheel. Weave the pastry strips, one at a time, into a lattice pattern. Fold the ends of the lattice strips under the edge of the bottom crust and crimp to seal.
5. Pour butter-sugar mixture over top of pie, coating the lattice, and allowing any remaining sauce to drizzle through the crust.
6. Bake in the preheated oven for 15 minutes. Reduce heat to 350 degrees F (175 degrees C), and bake until the crust is golden brown, the caramel on the top crust is set, and the apple filling is bubbling, 35 to 40 more minutes. Allow to cool completely before slicing.
Thank you very much… rich information about electronics.
alright so basically I'm speedrunning through some of the high school physics I forgot and has come back to haunt me in my course xD
Memory effect exists in resistors, too. A 000 smd resistor resists, after several use, it will become fully conductive. Smart batteries have such resistors inside the battery pack.
The “49” and the latter comment on that moment killed me as a subscriber. Nice video tho.
