A generator produces 240volts at 25 amperes If the mechanical and electrical power losses total 900 watts what is the efficiency of the generator?

If the generator produces 240v at 25 amps, this amounts to 6000 watts, so if the losses are 900 watts, the total power generated must be 6900 watts. The efficiency is then 600 (MORE)

Why can't mechanical efficiency be over 100 percent?

The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it p (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
