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

d. 12 A

Explanation:

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

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

is the potential difference across the resistor

is the resistance

Solving the equation for I, we find the current:

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
