Homework Statement


In the circuit shown, what is the potential difference VPQ?
Circuit schematic with a 2V cell and 2Ω resistor on the top-left branch, a 4V cell in the middle branch, a 1Ω resistor and 2Ω resistor along the bottom with a 1V cell, and a 3Ω resistor on the right, with points P and Q labelled.


Homework Equations


No relevant equations given in question

The Attempt at a Solution


Tried kirchhoffs law.

Tried to find equivalent battery and resistance but that doesn't seem to be possible.

You need to show what you've tried so we can see where you went wrong.
You can take photos of your working and post them here using the 'UPLOAD' button (ensure that they are clear and easy to read) or you can simply type out your equations here.
 
There will be counter-clockwise current around the right-hand "loop", and clockwise current around the left-hand "loop". Use these in Kirchoff.
