## Homework Statement

1. Find the power dissipated by 12 ohm resistor

2. What is the potential at points a,b,c,d?

## Homework Equations

P=I^2R

I=V/R

## The Attempt at a Solution

For a) 3v-IR-6v-IR=0

9v=I(18)

I=0.5

P=0.5^2 * 12 = 3 watts

But not sure if the ground changes anything

b) unsure if ground changes anything
