Question

The current through a 10-ohm resistor connected to a 120-V power supply is a. 1200 A d. 12 A b. 1 A e. 10 A c. 120 A

Answer 1

d. 12 A

Step-by-step explanation:

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

`V=IR`

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

`V=120 V` is the potential difference across the resistor

`R=10\Omega` is the resistance

Solving the equation for I, we find the current:

`I=(V)/(R)=(120 V)/(10 \Omega)=12 A`
