AC Generator works on which principle - Electromagnetic Induction

Today we are going to talk about AC generator and how AC generator works. You must have seen that there is an AC generator in many places. Mostly it is seen in big institutes, offices and weddings or even other programs. After all, why AC generator is found everywhere and why it is needed. Does it produce electricity or transfer electricity ? If it produces electricity, how does it do that? And how much electricity can it produce at one time? And what electrical appliances can it run?  AC Generator is a device used to generate a sinusoidally varying emf.  AC Generator is a device that converts mechanical energy into electrical energy producing an alternating emf.  The input of an AC generator is mechanical energy supplied by steam turbines, gas turbines and combustion engines. The output is alternating electrical power in the form of alternating voltage and current. AC Generator induces an EMF or Current in a loop through the change in its Orientation or a change in...

Explain the working principle of transformer and also its construction - Physics

You all must have seen a transformer in your area and you must have seen a transformer in many places. You must be wondering why transformers are installed in every area. Does the transformer make any electricity or is it installed like this? Nor does it generate electricity, so what is its function, why is it visible in every area? So today we will know how a transformer works and we study the working principle of transformer. A Transformer  is a passive component that transfers electrical energy from one electrical circuit to another circuit or multiple circuits.                                                                     Or A Transformer  is an electrical device that transfers energy from one electrical circuit to another using the principle of electromagneti...
