An AC generator produces alternating current. To convert an AC generator into a DC generator, which crucial component must be replaced?
A. The slip rings must be replaced with a split-ring commutator.
B. The split-ring commutator must be replaced with slip rings.
C. The armature coil must be made of aluminum.
D. The magnetic poles must be swapped.
Answer: Option A
Solution (By JKSSB Mock Tests)
An AC generator uses continuous 'slip rings' which allow the output polarity to reverse every half-rotation of the coil, generating alternating current. To produce direct current (DC), the slip rings must be replaced by a 'split-ring commutator'. This commutator reverses the connections to the external circuit at the exact moment the coil's current reverses, ensuring current flows in only one direction outside.
