A 60-watt bulb is plugged into standard house voltage of 120 volts. calculate the energy in joules consumed by the bulb in 24 hours. (round answer to nearest tenth.)

Watt is a unit of Power and we know that Power is simply the ratio of Energy over time. Therefore:

Power = Energy / time

Energy = Power * time

where time is in seconds therefore convert 24 hour to seconds:

time = 24 hours * (3600 seconds / hour) = 86,400 s

Energy = 60 Watt * 86,400 s

Energy = 5,184,000 Joules
