Kirchoff's Loop Rule

087 - Kirchoff’s Loop Rule

In this video Paul Andersen explains how Kirchoff’s Loop Rule can be used to calculate the voltage of different components of a circuit. The sum voltage throughout an entire loop will sum to zero following the law of conservation of energy. An analogy and several examples are included. In Physics 1 students should be able to apply Kirchoff’s loop rule to a simple circuit with a battery and resistor. In Physics 2 capacitors and parallel circuitry are included.

You have probably made me pass the physics course, thanks a lot and I wish all the good things happen in your life !

I’m currently an electrical engineering student, and it has come to my attention that students have trouble grasping the concept of Kirchhoff’s Voltage Law in many of the introductory courses. My colleagues and I set out to help these student by offering a technical description of the process to coincide with the course material. We discovered it was much easier to grasp this concept with analogies, as you did. We then provided a strategy for solving these problems by analyzing the circuit, choosing a loop, and finally applying Kirchhoff’s Law to solve for unknown variables. We hope this technical description will benefit struggling students.

Truly amazing channel you have Paul. Leaving small pauses after conclusions would help to realize and remember before the next part.

Thank you so much Mr. Andersen, you are the best.
Physics bless us all

[willya]

Thanks for sharing your videos. They are wonderful and easy to understand. The best videos about electrical ever seen.

[Itskelss]

Thank you a lot! I struggle with physics and this made me understand better about Kirchhoff's law.

[fastdollar]

thank you, I was so lost when we went over this in class. I'm grateful for this, I just needed a different look at it I guess.

[lukasherrmann]

you are the definition of a blessing my friend

[astroash]

Excellent description, very simple to grasp.

Also why would be there a potential drop across second capacitor, since the larger capacitor will store all the charge. unless the dielectric potential breaks.could you through some light

Can you please share whoch software you are using where you measure with the multimeter? Or is it just graphics?

[bhanubhaktasapkota]

So battery is a elastic rubber band holding charge on it and it releases charge around circuit, when a load comes it lose energy just like friction cause to lose energy of body which causes to lose energy of charge. But how it regain it energy from battery?

[sangurai]

We know that voltage drives the current around but at the end point of the source before entering is zero so does it mean no current there or current is in motion and only voltage drop?

[ProLeopardx]

Wonderfully explained, thank you so much.

[vishaalshiva]

Really helped me a lot. Thanks for doing this video

[danielkwon]

Thank you for helping me all the time, I use your videos a lot - you explanation is perfect!

I had one question about Kirchoff's Rule,
what happens if those 'loop' that we are working on has capacitor or Inductor?
how does the equation change?

Thank you very much~!

[vanillapie]

great educators are great communicators.

[ravitanwani]

Great Video.Which software were you using?

[davidoldscheuerman]

Thank you.
I do have a question.
How is voltage (potential difference) stored in the moving electrons? What I mean by this is when a current of electrons goes through a battery, how does the voltage give them power to carry out their functions, (ex. light bulbs)? Should I think of it as like Amplitude in waves? because the current is same all through the circuit. I just want to know how energy is delivered from the battery to the resistor?
