| January 18, 2021 | education
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.
