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
Verified Correct Answer: D.
Physical Principles & Numerical Solution
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.
