Resistors in Electric Circuits (1 of 16) Series vs. Parallel

Describes the rules governing the voltage, resistance and current for parallel circuits and series
circuits.
In a series circuit, the current is only able to flow through a single path. In a series circuit, the current is the same throughout the entire circuit. The voltage in a series circuit is divided across each of the resistors. If one of the resistors in a series circuit stops working, the current will not be able to flow through the rest of the circuit.

In a parallel circuit, the electrical current flows through multiple paths before returning to the power source. The voltage drop in a parallel circuit is the same across all of the resistors. In a parallel circuit, the current is divided up through each of the resistors. If one of the resistors in a parallel circuit stops working, the other resistors in parallel will be able to continue to working.

A resistor limits the electric current that flows through a circuit. Resistance is the restriction of current. In a resistor the energy of the electrons that pass through the resistor are changed to heat and/or light. For example, in a light bulb, the tungsten filament acts as a resistor that heats up because of the current going through it, causing it to glow. Ohm’s law, V = I x R, states that the voltage drop across a resistor is equal to the product of the current flowing in the resistor multiplied by the resistance of the resistor.

I needed a clear reference for my son who is starting with this in Grade 9 during home isolation Covid 19. The school referenced a different course which was unclear to him. This is much more clear and well taught for anyone to learn. Well done!

I'm taking an Hvac certification course and your videos have been a very valuable resource to learn more about series and parallel circuits.
Thank you very much 😊.

I don't know how you're not the number one physics channel excluding Walter Lewin. Another excellent video

This video, and the video of capacitor in series vs. capacitors in parallel are AMAZING, I was able to understand with detail every single difference among; because of this, I love this electricity concept, I am considering switching my majors, from computer science to electrical engineering.
Thank you!

It is absolutely helpful and i like your teaching method step by step

[cliffjones]

The circuits shown provide a voltage source, not a --voltage gain-- because there is not an increase of voltage through amplification. (gain). However the illustrations are very good and the detailed explanations are spot on. Thanks

[mmartinez]

Good stuff, very helpful. I also appreciate the format you use for your drawings, i.e. the black background with colored text. For me at least it's easier on the eyes.

Awesome video. I think your channel is gonna help my pass my Engineering Circuits Class

[ishirsharma]

Thanks so much guys! I am definitely going to ace my 8th Grade exams on this! A* here I

I love your channel. Do you have a teachers pay teachers link🙏. I hope so. Great videos. Keep up the good work. Thank you

[bobbyoctaviano]

As always, thanks again so much for being so thorough. Cheers Doc Brian. Bobby :)

I keep coming back to this video. It's amazing

[rosalindfahy]

Hi! Thanks for the great explanation. I was wondering if you could help me with a question I have. My book says that if you place more resistors in a parallel circuit the equivalent resistance decreases because "each new resistor provides an additional path for current, thereby increasing the total current while the potential difference remains unchanged." I don't understand how the total current could be increased from the original? Where does it come from? Sorry for the long comment and thanks again for providing these videos. They help a lot.

This is amazing. It helped me a lot 😀😀

This was really helpful. Thank you so much!

Hello! I don't understand the part about current in series circuits. How the currents through different resistors could be the same, if only they have the same resistance? Is equation I(B)=I(1)=I(2)=I(3) true if the resistors have various resistance? What about ohm's law I=U/R?

[RumbleStriker]

Extremly amazing sir. But one thing keeps revolving in my mind. Sir when a single resistor is connect in an simple circuit. .Does the current reduce after flowing through the resistor or only at the resistor or does it remain the same anywhere? How and why?. Pls sir hope u help me

[thomasalexander]

Question, about finding the total resistance on parallel DC circuits. The 1 over the RT in the equation is the voltage that the resistance can get? It can be 1 or 12, 24 or anything for that matter? Or am i of subject?

[bestmoviesrecapsoriginal]

sir please am a student and i want to start teaching maths on youtube, please what software do you use

[princessrazon]

The explanation is good, im reading the eng sub coz your voice is really deep man cant understand hehe
