Audrina Abbott · Answer 1

Solving for the applied voltage can be done by using Ohm's Law. The law states that the current is equal to the voltage divided by the resistance. This can be rewritten in terms of voltage as follows:

V = I * R

Given: I = 9A; R = 43 ohm

Substituting the given values:

V = 9 * 43

V = 387 Volts
