- In this informative video, we dive deep into the fundamental concepts of electrical circuits. Join us as we unravel the mysteries of current, voltage, and resistance. Learn how current is measured in Amperes (amps), the potential difference in volts, and the resistance in ohms. By drawing parallels to the flow of water through a pipe, we simplify these concepts, equating water pressure to voltage and the volume of water to amperage. Discover the significance of resistance, akin to friction in the pipe, hindering the flow of current. We also explore Ohm's Law, a cornerstone of electricity, which mathematically relates voltage, current, and resistance. Find out how this law highlights the proportional relationship between current and voltage. Join us on this journey of understanding electrical basics, as we demystify amps, volts, and ohms. Watch now and grasp the core principles that underpin the world of electrical circuits!

I had a physics teacher who was 6'2" 250 lbs former merchant marine and boxer, who would occasionally scream at us, "whats Ohms law?!?!" And I never remembered.
6.2 250 yelling at yall you sure he wasn’t a coach lol
@@marcuslong24 Ha he wouldve been a good one.
@@PeaceManBro
Yo, he never tried? 😭
@@ivoryas1696 He sold hot pockets out of a freezer in his class, woukd make us de-sauter parts out of old vcrs he would sell on the side and ended up being fired for wrestling some kid that challenged him.
Students across the world have access to the goldmine of such educational content out there which previous generations didn't had.
i was just thinking this... i studied electrical engineering 20+ years ago... no youtube... had to read the textbooks and listen to poor lectures.
Oh my god understood .....thank God I understood finally😅😅
👍
thank you a lot! amazing comparison with water pipes:3
Glad you liked it!
For real ❤
The more I grow up the more science and magic sound similar
Question here, if the pipe of water had no pipe on one end but water was flowing out, would that part then be 0 ohms?
Ohm was a plumber 😎
I never understood what ohms law was thanks
Nice 😊
Thanks 😊
I'm a newbie to the electrical world.
So if Ohms law states "the higher the number amps, the greater the amount of volts" How are high current low voltage situations possible?
It all depends on the current. You can have high current low voltage situations depending on the resistance - if the resistance is too high, you can have a small amount of current flowing through the circuit with a high potential difference (volts). For example, in power lines, you have a high voltage but very low current flows through the lines.

Thanks for the response, electricity is confusing especially when learning. 🤣
If I remember correctly, the higher voltage is needed / used to allow for the long distance power transmission?
It's mind blowing🎉❤😂
❤ Nice
Thanks 🤗
Please tell me what is importance of i=v/r and p=ei
Voltage is usually constant which reflects a difference between two points but current and resistance are inversely proportional. Increase resistance, decrease amps and vice versa.
Draw a triangle. Inside on the top, put an E for voltage. Under that on the left put I for current. On the right, put R for resistance. To find an answer, just cover the one you want to know, and that is your equation. To find E multiply I times R. To find I divide E by R.
what about wattage ?
current is rate at which charge flows w.r.t time. I= Q (charge)/Time. Voltage is Energy/Charge.
Image showed 20 amps and 19 voltage...
First comment after exam 😂😂😂
Isn’t it E for volts not v ?
Thank you ❤🎉😢
What 😯
P=UI²
Very good explained ...
Thanks and welcome
If Voltage is Current * Resistance, then why in my breadboard voltage doesn’t change after resistor?
Because you have a constant voltage supply so only the current changes. If you had constant current source the voltage would change.
@@laserdiode how do I know if my power supply is constant voltage or constant current? How about li ion batteries?
@@caunt.official Almost every power source is more or less constant voltage batteries included. Some lab bench power supplys have constant current modes
You got volts and amps the wrong way around with the water example. Amps are the current not Volts.
is the higher the number in amps than voltage because energy is lost through the friction aka ohms when it’s traveling?
Bad example - incandescent light bulbs do not follow Ohm's law. Neither do electrolytes, semiconductors or gas discharge tubes. Only metals follow it and at low current densities too.
Everything follows ohm's law. The different things you said just don't have constant resistances so you cant predict them in different conditions using ohms law
@@laserdiode Everything does not follow Ohm's Law, even metals don't follow it at high current densities. Metals also change resistance with different conditions e.g. temperature.
In every single case ohms law holds. There is no way it wouldn't hold because resistance is literally defined to be voltage drop dividend by the current. If you use ohms law to predict the voltage and the current in different conditions you always assume that the resistance stays the same. If you do that to a light bulb and get an incorrect answer it doesn't mean that ohms law was wrong but that your assumptions were wrong

Your too speedy
Kaka Bola ji samajh nahin aaya😂😅
Ohm’s law has been proven to not work
no
