STEP 0: Pre-Calculation Summary

Formula Used

Overall Efficiency = Output Power/Input Power
η_o = P_o/P_in
This formula uses 3 Variables

Variables Used

Overall Efficiency - Overall Efficiency is the ratio of useful output of a system to the total input applied to the system.
Output Power - (Measured in Watt) - Output Power refers to the product of current and voltage at the output terminal of a dc generator.
Input Power - (Measured in Watt) - Input Power refers to the power input required to rotate the armature of the generator, which in turn generates electrical power. The mechanical power is provided by an external source.

STEP 1: Convert Input(s) to Base Unit

Output Power: 120 Watt --> 120 Watt No Conversion Required
Input Power: 220 Watt --> 220 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula
