How much energy is needed for an hour of 100W light bulbs?

These tasks: t (duration of the taken light bulb) = 1 hour (in SI t = 3600 s); P (light bulb power) = 100 W.

The energy that the taken light bulb will consume in 1 hour is calculated by the formula: Q = P * t.

Calculation: Q = 100 * 3600 = 360 * 10 ^ 3 J = 360 kJ.

Answer: To operate the taken light bulb, you need 360 kJ of energy.
