Question

A circuit with a battery, a 2 Ω resistor, a 13 Ω resistor, and a 29 Ω resistor in series. The total current is the system is 5.2 A. What is the voltage of the battery?

Answer 1

Resistors in series:

2Ω

13 Ω

29 Ω

Rt = total resistance = 2 + 13 + 29 = 44Ω

Total current = I = 5.2 A

Apply Ohm's Law:

V = I x R

V = 5.2 A x 44 Ω = 228.8 V

Voltage = 228.8 V
