I can describe how a dynamo works to generate DC and how an alternator works to generate AC.
Show transcript
Rotating a conducting loop in a uniform magnetic field induces a potential across the ends of the loop.
An electrical generator can be made in the same way as an electric motor.
A DC generator (dynamo) generates a varying DC current.
The connections in an AC generator (an alternator) are different to those of a dynamo.
An alternator makes an alternating current that repeatedly reverses direction as the coil spins round.
