Task data: t (duration of the lamp used) = 1 h (in SI t = 3600 s); P (lamp power) = 60 W.
The work of the electric current in the lamp used for 1 hour of operation is calculated by the formula: A = P * t.
Let’s calculate: A = 60 * 3600 = 216 * 10 ^ 3 J (216 kJ).
Answer: In 1 hour, a current of 216 kJ will be accomplished.
