Find the potential diffrence to send the same current, Physics

Assignment Help:

A resistor of 8Ω is connected in parallel with one of 12Ω and the combination is connected in series with one of 4Ω.

A p.d. of 10V is applied to the circuit.

The 8Ω resistor is now placed across the 4Ω resistor.

Find the p.d. needed to send the same current through the 8Ω resistor.
