Question

Did I solve this problem correctly?

Answer 1

There is a current of 0.25 A in the circuit of FIGURE P31.42. What is the power dissipated by R?

Answer 2

My attempt:

12-12(0.25)-6(0.25)-6-R=0

R= 1.5 ohms

Answer 3

Using Kirchoff's Rules

Answer 4

Why didn't you multiply R by the current?

Answer 5

I'm looking for R

Answer 6

Ohhh I see what you mean, I forgot to multiply by the current in the equation

Answer 7

I only have R, i need voltage

Answer 8

So now I get 6 ohms.

Answer 9

Well there's essentially 6V, and 6+12+6 ohms, which does give a current of 0.25A.
