Rearrange the equation current = voltage/resistance to express ?resistance? in terms of current and voltage. Then solve the following: A certain device in a 120-V circuit has a current rating of 20 A. What is the resistance of the device (how many ohms)?

Step-by-Step Solution:

Answer : Step 1: We know that according to ohm’s law V = IR Rearranging we get I = V/R Now

Step 2 of 2
