Consumption 80702

A current of 500 mA passed through the filament of a light bulb with a resistance of 400 ohms. What is the consumption of a light bulb in 5 hours?

Correct answer:

W =  500 Wh

Step-by-step explanation:

R=400 Ω I=500 mA A=500:1000  A=0.5 A t=5 h  P=R I2=400 0.52=100 W  W=P t=100 5=500 Wh
