A generator manufacturing company accidentally made an AC generator instead of a DC generator. To fix this error,
- A. the magnetic field needs to be made stronger
- B. the split rings should be replaced with slip rings
- C. the number of turns of the armature coil needs to be decreased
- D. the slip rings should be replaced with split rings
Correct Answer: D. the slip rings should be replaced with split rings
Explanation
An AC generator uses slip rings to transfer the induced current smoothly to the circuit. A DC generator uses split rings to transfer the induced current to the circuit and also convert the induced AC into pulsating DC. So, to convert an AC generator into a DC generator, the slip rings needs to be replaced with split rings.
