Question

An electric generator produces an electromotive force (e.m.f.) of 200V and produces a current of 3.0 A in a circuit. The generator is driven by an engine with a power of 2.4 kW. What is the efficiency of the generator?​

Answer 1

Below

Step-by-step explanation:

power out = V I = 200 * 3 = 600 W

Power in = 2400 W

600 W / 2400 W X 100% = 25% eff
