Multiple choice

A 500 watt toaster is connected to a 120 V household outlet, then calculate the resistance of the toaster.

  1. 28.8 ohm

  2. 7200 k ohm

  3. 0.034 ohm

  4. 4.166 ohm

  5. 0.24 ohm

A Correct answer
Explanation

V = 120 V P = 500 W Find: R Use the P = V2 / R equation to calculate the resistance: R = V2 / P = (120 V)2 / (500 W) R = 28.8 ohm
