Problem

Two identical rectangular loops placed side-by-side share a

4\,\Omega

resistor between points P and Q. Each loop contains a

6\,\text{V}

battery whose positive terminal is at P and a series resistor of

2\,\Omega

. Assuming clockwise currents in both loops, calculate the current in the

4\,\Omega

resistor.
