Answer:
Dynamos and Generators convert mechanical rotation into electric power.
Dynamo - a device that makes direct current electric power using electromagnetism
Generator - used to describe an alternator that creates AC power using electromagnetism.
Explanation: so dynamo makes direct electric power using electromagnetism. A generator creates AC power using electromagnetism
