The generator current is more steady.
Answer: Option D.
<u>Explanation:</u>
A direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. The basic principles of operation are the same as those for synchronous generators. ... The field is produced by direct current in field coils or by permanent magnets on the stator.
Generators don't actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
