Copper Loss is constant for which type of DC Generator

by

Copper Loss is constant for which type of DC Generator:

  1. Shunt generator
  2. Series generator
  3. Both of these
  4. None of these

Correct answer: 3. Both of these

Explanation: The copper losses can be expressed mathematically by formula:

P = I2R

In a generator, the output voltage at the terminal should and must remain constant. To achieve this, the field produced by the shunt and series field must remain constant. For satisfying this, the current passing through the fields must also be constant.

The resistance of series and shunt field is always constant once it is designed.

And thus the copper losses are always constant.
