A DC generator works on the principle of

A
Ohm's law
B
Joule's law of heating
Correct answer
C
Faraday's laws of electromagnetic induction
D
None of the above

Solution

A DC generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. It operates on the principle of Faraday's laws of electromagnetic induction. Faraday's law states that a current will be induced in a conductor which is exposed to a changing magnetic field.

Hence, the correct answer is option: 'C'.
