Question

In this circuit, which resistor will draw the least power?

The power will be the same for each resistor.
R1
R3
R2

Answer 1

R1? @Shadow

Answer 2

The voltage isn't constant in a series circuit, and thus will be reduced as it flows through each resistor. This will result in lower power in the resistors following R1.

Answer 3

That's why series circuits aren't good when you want lights to have the same brightness. Parallel circuits are better, which is what Christmas lights consist of.

Answer 4

If Christmas lights were a series circuit, each following bulb would be less bright. Keeping that in mind, which resistor do you think will draw the least power?

Answer 5

So then it would be Resistor 3?

Answer 6

Yes. This is because the current flows out from the positive end, and is received at the negative end.

Answer 7

Thank you

Answer 8

No problem
