Question

need or necessity of electric generator​

Answer 1

In order to avoid interruption on whatever we do that require electricity,generators can provide temporary supply of electrical energy. Generatorsare machines that convert mechanical energy into electrical energy. You canhave them work once a power interruption happened

The fuel system ensures the generator has the necessary raw materials needed to provideelectricity by initiating the internal combustion process. Without fuel, combustion can't take place and the generator can't convert the mechanical energy created into electrical energy.

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines,gas turbines, water turbines, internal combustion engines and even hand cranks.
