Description
An electric generator is a machine that converts mechanical energy into electrical energy. An electric generator is based on the principle that whenever flux is cut by a conductor, an e.m.f. is induced which will cause a current to flow if the conductor circuit is closed. The direction of induced e.m.f. (and hence current) is given by Fleming’s right hand rule.

mixture tends to ignite spontaneously in the
engine’s cylinder before it is completely
compressed and ignited by the spark plug. This
may result in “Engine knocks” resulting in “loss
of power.
