Question

An electrician needs to know that the relationship between amps, volts, and resistance is

expressed in the formula V = IR where V is volts, I is amps, and R is ohms. How large a
resistance is needed to produce 8 amps from 184 volts?

Answer 1

R = 23 ohms

Explanation:

Start with V = I*R. Solve for R: R = V/I

Here I = 8 amps and V = 184 volts, and so

R = (184 volts) / (8 amps) = 23 ohms
