Electric Power Efficiency (η)

η is the efficiency in percent (%). P in is the input power consumption in watts (W). P out is the output power or actual work in watts (W). Example. Electric motor has input power consumption of 50 watts. The motor was activated for 60 seconds and produced work of 2970 joules. Find the efficiency of the motor. Solution P in = 50W. E = 2970J
