A motor having an efficiency of 0.8 uses 800 J of electrical energy. The output energy of the motor is:
Question
Solution 1
The efficiency of a motor is given by the formula:
Efficiency = Output Energy / Input Energy
In this case, we know the efficiency (0.8) and the input energy (800 J). We can rearrange the formula to solve for the output energy:
Output Energy = Efficiency * Input Energy
