Answer:
A. 85 W
Explanation:
case 1: toaster is connected to 130 V outlet
P = Power rating of toaster = 100 W
R = Resistance of the filament
V = Voltage of the source = 130 Volts
Power is given as
R = 169 ohm
case 2: toaster is connected to 120 V outlet
P = Power dissipated
R = Resistance of the filament = 169 ohm
V = Voltage of the source = 120 Volts
Power dissipated is given as
P = 85 W
