Question

A current of 10 ampere flows through an electric oven of resistance 80 ohm for 1 hour calculate the rate of generation of heat

Answer 1

Answer:

Explanation: The rate of production of heat is 8 kj/ hr.

Answer 2

Answer:8000J8KJ/hrExplanation: I = 10A R = 80ohm t = 1 Hour using Joule's law of heating;H = I² Rt = 10² × 80 × 1 = 100×80×1 = 8000 J = 8 KJThe rate of generation of heat by the oven = 8 KJ/hr
