Full Answer

A basic transformer consists of two windings around a shared core. The process of electromagnetic induction, through which electricity reacts to magnetism, transforms electric energy from one set of circuits to another. This allows the frequency of the electrical energy to remain stable and unchanged. Transformers vary widely in size and power, and power grid transformers can weigh hundreds of tons. Transformers are responsible for the modern utilization and distribution of electrical energy.
