Question

What type of periodicity does current produce from a given dynamo?

Answer 1

Answer:

A dynamo is an electrical generator that creates direct current and if it is continous then it will be with zero frequency

Explanation:

A dynamo is an electrical generator that creates direct current using a commutator. Whenever there is commutation the output will always be in the form of a one sided signal and if it is continous then it will be with zero frequency.

The DC does not mean permanent current, its value can vary in time, however the direction never changes, i.e., never crosses zero line. So under that understanding, if we have periodic positive pulses, the fundamental frequency would be f=1/T, where T is a period of pulses, however dynamos generally don’t produce pulses rather they give a continuous direct current
