Today is my birthday and tomorrow is «pre-exam test» in physics. So this is the best birthday gift I could get! It’s literally the only chapter I need to practise on before tomorrow. Thank you so much Jason, this comes at perfect time as always! 👏
You are an amazing teacher, slowly making my way through all your videos. You can tell someone understands their subject/ trade really well when they're able to break it down into its most basic components and make anyone understand it. Thank you 🙏
Professor Math and Science Tutor, thank you for an excellent explanation of Electric Current and Short Circuits in everyday Electrical Systems. For students in Electrical Engineering, Electrical Current/Short Circuit is a very important topic to learn, due to the dangers of these two systems. This is an error free video/lecture on TH-cam TV with the Math and Science Tutor.
Here's a couple of statements that are true that I hope you will explain. All the available voltage should be used up across the load. Adding resistors in a series circuit is different than adding up the resistors in a parallel circuit correct. Thanks for the great videos and info.
I have watched maybe 5 videos where Jason has explained the rules of voltage and current and resistance so it is starting to sink in that he thinks this is a very important building block to understand electricity! Hope you have a great Father's Day Jason!
Another terrific lecture, Jason. I remember watching freight trains being shunted when I was a youngster. When another freight car was shunted on to the end of a mile long train, the jolt would be propagated through the entire length of the train to the locomotive in a second or two even though the actual movement of each car was very small. I think of this when I think of the difference between the speed of electrons in a conductor and their speed of propagation. A small point which I'm sure you'd be aware of: the resistance you measured in the cold light bulb in the circuit you showed was quite low, and didn't account for the current difference using Ohm's law. The resistance would have been much higher when the light bulb was actually illuminated.
High speed tutorial this one is, mr Gibson, many joules were burned during the making of this video 😆 thanks for all of your work, I just subscribed to your website, it's teaching me a lot. Best regards from the Netherlands.
Sir, can you later do a video talking about flemings left hand and right hand rule? I love learning about electricity and magnetism. It's fascinating to me. Thank you for the great content and for taking the time out of your busy life to teach us
Professor, what I didn't understood is where is the Watt coming from, please!? What creates the watt and for example how many watts can carry a 220V-240V AC? Or how many Watts/Volts are?Also, please, where are the Volts created from and what creates the electric current? I understood that I-the amperage is made out of electrons which are the only ones that moves through a circuit and jump diagonal on Protons and creates holes behind them, from here the name "Hole current", but what is forming (generating more of) those atoms containing the positive and the negative charge? Hat off, I bow! Thank you very much for your time and kindness!
Jason talks about copper being a great conductor and of course it is! I made a mistake years ago when I had a home project requiring to rewired and I knew if I used aluminum wire which is also a good conductor you can save a lot of money! However the aluminum wire is very stiff! You also have to increase the wire size from copper such that if the copper was 12 AWG you have to use 10 AWG for aluminum. I made it work and the power co said I did a good job but it was very hard and I will never do it again!
I have a few more topics in the sequence before I get there, but I will definitely be doing Kirchhoff’s laws with practical circuits in measuring everything.
What is electric current? What is electric current? Electrons flow in a conductor? How do electrons flow in a conductor? Like many cars driving down the highway? Or is water flowing in warer pipe? What is a highway in a conductor? What is the water pipe in the conductor? Why don't electrons flow to the positively charged nucleus? What magic keeps electrons away from the nucleus? Is the speed of electrons flowing in copper wire the speed of light? If not, how could electricity travel at the speed of light? If so, how can electrons accelerate at the speed of light? In fact, Atoms are not made from charged particles as scientists told. All atoms consist of indestructible, electrically charged multiple layers hollow sphere and internally charged solid sphere. Outside each atom is a layer of negatively charged liquid that scientists mistaken for electrons. This negative charged liquid attaches to non-metal atoms due to their outer layer is positively charged and floats on metal atoms due to their outer layer is negatively charged. The floating liquid of a conductor conducts electricity. Electricity is flow in conductor instantaneously, similar to hydraulic fluid flow through hydraulic systems. The voltage of the electricity is proportional to the speed at which the floating liquid moves.
“hole current” an explanation of a previous unknown term. The plus side of the DC battery is pulling electrons. While the negative side of the battery is pushing (repelling) electrons.
If you wonder the confusion why current goes the different direction as electrons. You can thank Benjamin Franklin for that. He knew that there were glass and resin electricities and they they canceled each other. He named the glass electricity positive and the resin electricity negative. Had he done the opposite everything would be so much simpler. 150 years later J.J. Thompson discovered electron and found it was negative.
Can Sir explain why same voltage different ampere like power supply or batery some stuff voltage same but ampere different..... 1 more i want to ask sir.. true or not current flow depend on load we use? Tq sir
I’ve always heard that a circuit “draws” a certain amount of amps from the power source, which is why the source can be higher amperage than what the circuit is requiring. So uhh… could you also think of voltage as the “pull”, or how could those concepts coincide with each other?
Voltage is the pressure of a circuit a battery has a certain amount of pressure like 6 V or 12 V what current the wires can handle is determined by the fuse size in a series circuit a 10 amp circuit with 12 V pressure will be able to handle 10 A of current although a circuit can have a spike in current which may bring a 10 amp circuit to 12 A for an extremely short period of time so the Fuse does not blow so you can measure how many electrons flow in a circuit is 6.25 million million million electrons in one point of a wire in one second of time so we can actually measure the flow of electricity in so far as the flow of current in a wire forget all the scientific crap if you’ve got a 10 V or 12 V circuit and a ten amp fuse is blowing that means the resistance has dropped in the circuit carrying more than 10 A of design so one can determine how much less resistance is in a circuit when the fuse is blowing by putting increasing sizes of fuses in the circuit so if a tenant fuse blows in a 20 amp fuse does not that means there’s been almost double or less of the current flow through the circuit the less the resistance the higher the current flow another word 6.25 million million million Little Eddie electrons are CountableWith an amp meter to tell the mechanic how many amps are flowing to the circus nothing is magic voltages pressure electrons are negative charge little Eddie electrons in the resistance is the amount of resistance the current can provide in the circuit more resistance means more heat more heat blows the fuse or melts the wires in a short circuit is one where there’s less resistance much more current flow and the fuse blows out
And please quit talking about that the positive is where the current flows from that is wrong and it screws everybody up who’s not an electrical engineer electricity pressure flows from minus to plus little Eddie electrons negatively charged and Lil Eddie always wants to go home which is positively charged electricity flows from the minus terminal to the Plus terminal always electron flow from where there are more electrons to less electrons 😊minus to plus
In other vids he has explained what whole current is and why in electrical engineering we use positive values to make it easy on the math aspect... With is a mirror image of the negative values of electrons... Math and science is mvp and should not take bs from anyone
Today is my birthday and tomorrow is «pre-exam test» in physics. So this is the best birthday gift I could get! It’s literally the only chapter I need to practise on before tomorrow. Thank you so much Jason, this comes at perfect time as always! 👏
Awesome!
Despite being taught electricity/currents/volts etc in Physics at school, your videos are the first time I really understood it. Much appreciated.

Happy new year! 🎉 Thank you very much for your time and commitment!
Very good teaching, can be understood by non science / engineering students.
Thank you.

Where has this channel been all my life?! I'm learning all kinds of things. Thank you very much!
Welcome!
Excellent, really love listening to your presentations.

Be happy good teacher in your life
these are amazing lessons when we have demonstrations. Its is incredibly useful and easier to understand. you are a fabulous teacher sir.
I enjoyed the physics presentation on electric current, and what is a short circuit.
Sir, can you later do a video talking about flemings left hand and right hand rule? I love learning about electricity and magnetism. It's fascinating to me. Thank you for the great content and for taking the time out of your busy life to teach us
Very informative in a simplified way. Thank you
"I think you're more than incredible teacher to me... Your name is superstar incredible teacher."
Awww thank you!
@@MathAndScience I wish you were my teacher since I was a kid then you're full of knowledge man!!!
THANK YOU, GREAT TEACHER !
Super sir
Fascinating stuff. You are an excellent educator. Thank you.

Another great lesson. Again 💥
Thank you!
Thank you for sharing this knowledge, Can you please make more videos on short circuits ? I’m having a hard time understanding them.
Check out his website, it's a treasure trove of information
great work and ver clear!! keep it up
Thank you!
Without dielectrics, we'd have nothing but shorts.
Nice 👍
Great lesson. Thank you

best teacher ever❤ but curious when are you gonna review kirchoffs laws?
I have a few more topics in the sequence before I get there, but I will definitely be doing Kirchhoff’s laws with practical circuits in measuring everything.

This is Awesome. thank You
I think current in a wire is acted upon by both the applied voltage and pull of fixed positive ions.
Appreciate your video,it helped me a lot.💝💝
Glad it helped!
Awesome

You didnt say much about the danger of shortcurcuit. When does the amp gets risky for us, and how much resistance should we add to a curcuit?
Fun facts 🏋️🏋️🏋️💯💫
love your work thanks
Welcome!
Wow thanks tr🎉 ,, 💯 pleasure to have around indeed we love sir ❤
Thanks so much!
@@MathAndScience well , just inquiry , how can I become a member that is to be able to watch all the lessons in the channel sir ?
Can Sir explain why same voltage different ampere like power supply or batery some stuff voltage same but ampere different..... 1 more i want to ask sir.. true or not current flow depend on load we use? Tq sir
I think applying ohm's law to a metallic conductor is an extreme case, since it act as a short circuit.
I’ve always heard that a circuit “draws” a certain amount of amps from the power source, which is why the source can be higher amperage than what the circuit is requiring.
So uhh… could you also think of voltage as the “pull”, or how could those concepts coincide with each other?
The load (resistor) is pulling current.
