Explain efficiency, Physics

Assignment Help:

An electric motor with a load delivers 5.2 hp to its shaft (1 hp = 746 W). Under these conditions, it operates at 82.8 percent efficiency.

a. How much current does the motor draw from a 240-V source?

 

Efficiency = (Efficiency is defined as the ratio of power output to power input.)
