Q1:

What is the power dissipated by R1, R2, and R3?

A P1 = 0.13 W, P2 = 0.26 W, P3 = 0.12 W

B P1 = 0.26 W, P2 = 0.52 W, P3 = 0.23 W

C P1 = 0.52 W, P2 = 0.92 W, P3 = 0.46 W

D P1 = 1.04 W, P2 = 1.84 W, P3 = 0.92 W

ANS:B - P1 = 0.26 W, P2 = 0.52 W, P3 = 0.23 W

I think that the 0.52 W is wrong and that 0.46 W should be the answer.
So, it should be P1=0.26 P2=0.46 & P3=0.23.
