Question

There is a 120 V circuit in a house that is a dedicated line for the dishwasher, meaning the dishwasher is the only resistor on that circuit line. If the dishwasher draws 18 A of electricity, what would the resistance of the dishwasher be? Round the answer to the nearest hundredth of an ohm.

Answer 1

V=120

I=18a

V=IR

R=V/R

R=120/18

R=20/3

R=6.6Ω

Nearest to 100=6.6×100=66Ω
