Question

A current of 9 a flows through an electric device with a resistance of 43 . what must be the applied voltage in this particular circuit?
a. 387 v
b. 4.8 v
c. 387 a
d. 4.8 a

Answer 1

Voltage, V = IR

Where I is current in Ampere, R is Resistance in Ohms.

V = 9A * 43 Ω

V = 387 V

Option A.
