A 9.0 §Ù resistor and a 53.0 §Ù resistor are connected in parallel to a battery, and the current in the 9.0 §Ù resistor is found to be 1.41 A. Find the potential difference across the bat- tery.

Answer 1

R1 = 9.0 ohms
R2 = 53 ohms
I1 = 1.41 Amps = current through R1.

V = I1 * R1 = 1.41 * 9 = 12.69 Volts. =
voltage across battery.
