Answer:

d. 12 A

Explanation:

The current and the voltage in a resistor are related by Ohm's Law:

[tex]V=IR[/tex]

where

V is the potential difference across the resistor

I is the current in the resistor

R is the resistance

In this problem, we have

[tex]V=120 V[/tex] is the potential difference across the resistor

[tex]R=10\Omega[/tex] is the resistance

Solving the equation for I, we find the current:

[tex]I=\frac{V}{R}=\frac{120 V}{10 \Omega}=12 A[/tex]
