Question on: JAMB Physics - 2023
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
Ask EduPadi AI for a detailed answer
Correct Option: D
In an AC generator, slip rings are used to allow continuous rotation of the coil in the magnetic field. In a DC generator, split rings (also known as commutator) are used to convert the alternating current generated in the coil to direct current. Therefore, to convert an AC generator to a DC generator, the slip rings should be replaced with split rings.
