Question

A commutator is used in a DC dynamo.

• A. True
• B. False

Answer 1

The correct option is A True

1. A dc dynamo is a device that converts mechanical energy to electrical energy (direct current).
2. The function of the commutator is used to collect the current from the armature and send it to brushes thereby avoiding the reversal of the current direction.
3. Hence, it is used in DC dynamo to produce direct current or unidirectional current

Hence, the given statement is true.
