Question

The power supplied to a typical black-andwhite television set is 48.1 W when the set is connected to 72 V. How much electric energy does this set consume in one hour? Answer in units of J..

Answer 1

Energy consumed = 1.73× 10⁵ J

Explanation:

Given:

Power P = 48.1 W, Time = 1 Hrs= 3600 S

Formula of Power = Energy / Time

⇒ Energy = Power × Time

Energy = 48.1 W × 3600 S = 173,160 Joule = 1.73× 10⁵ J
