A 110-V toaster is rated at 1200 W. If the current increases past 20A the circuit breaker flips, and power shuts off to the circuit.

A) How many toasters can you plug into the same outlet/circuit (assuming you have enough plugs) before the total current to all of the toasters is greater than 20 Amps? What is the resistance of the toaster?
