DC Circuits - Power Dissipated in Resistors

Physics Ninja shows you how to calculate the power dissipated in a network of resistors.

There are loads of students suffering in University who would love to have teachers like you.

Wow. This is the clearest explanation i found on youtube. Thanks a lot.

[carolineseffen]

Wow nice video, I would like to thank you from the middle east, your teaching is better than instructors at college ❤, Many thanks

[ethancole]

Have a test tmr and compared to my online teacher who is super dry and doesn’t really try to explain anything you are god sent

[LOKESHKUMAR-upqh]

Thanks a lot your explanation is very good

[cacerxszz]

Subscribed 😊 this helped me answer my assignments
Sends love from philippines

[princemarasigan]

Thanks alot! the clearest DC circuit power dissipation in youtube hahaha

bill burr is great physics teacher who knew

In India, this chapter is in last year of our schools. When do you study it in your countries?

How does this problem change when you have two voltage sources? Do you use superposition theorem?

[prateeksharma]

In which standard u guys learn this thing in USA tell me in from middle East

I thought your cursor was a bug on my screen

Nice explanation
but why 1i2 = 3i3 ??
i didn’t understand this point💔

So, why then, when I connected 10K 0.25W resistor to the 12V battery it got hot enough to burn my finger? According to the calculations: 12v/10000 Ohms = 0.006Amps; And then 0.006A*12V = 0.072Watts. While resistor tested was 0.25W - way more then 0.072Watts required. Why is it getting melting hot?

[Faisal-fvgg]

Why the power calculated from the battery not negative !??

[miguelquintana]

im confused where do you get 3/3 from 1/1+1/3

[zorack]

Shouldnt the P.D across the 1ohm resistor and the 3 ohm resistor be 20V, as it is parallel to the battery?

[rodrigolerdodetejada]

How do you solve if instead of a voltage you have 5Amps?

[wassy]

what do we do when we have 3 resistance in a parallel circuit instead of 2? :(

You go through the smallest steps which isn't necessarily good. At this stage students can obviously understand the calculation steps while you just go through the conceptual steps. It was hardly a 2 or max 3 minutes question that you explained in 13 minutes. You explain quite clearly though.
