## Homework Statement

V1 = 15 V

V2 = 4 V

I = 2 A

R1 = 3 Ohm

R2 = 4 Ohm

R3 = 8 Ohm

R = 2 Ohm

In this part of the question, I have to solve for the voltage across a and b

R isn't listed as a resistor in this circuit because that comes in a later part of the question (which I can do).

## Homework Equations

KCL and KVL?

## The Attempt at a Solution

My initial thought was to do KVL across the entire circuit. So that means what I did was I had

-V1 - V2 + (R1 + R2) * I

However, this proved to be wrong

Then I tried to do voltage splitting on the resistors. Which means

[R2 / (R1 + R2)] * (V1 + V2)

This is also wrong

How do I do this question?
