A generator manufacturing company accidentally made an AC generator instead of a DC generator. To fix this error,
the magnetic field needs to be made stronger
the split rings should be replaced with slip rings
the number of turns of the armature coil needs to be decreased
the slip rings should be replaced with split rings
Uitleg
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.
