      What is the difference between a direct current and an alternating current? How many times does AC used in India change direction in one second? [NCERT Exemplar]

    Answer:

                      Whenever the magnetic flux linked with a circuit changes, an induced e.m.f. (electromotive force) and hence induced current is produced in the circuit. This phenomenon is known as electromagnetic induction and is used to generate electric current in a generator or a dynamo.
