Which of the following loss in a D.C. generator is dissipated in the form of heat?
Correct answer: D. All of the above
- A. Mechanical loss
- B. Core loss
- C. Copper loss
- D. All of the above
Explanation
Mechanical losses, core losses and copper losses all ultimately appear as heat: friction and windage heat moving parts, core losses heat the iron, and copper losses heat the windings. Therefore all listed losses are dissipated as heat.
