Transformer operations refer to the processes involved in converting electrical energy from one voltage level to another using a device called a transformer. This device consists of two or more coils of wire, known as windings, wrapped around a magnetic core. When alternating current flows through one winding, it creates a magnetic field that induces a voltage in the other winding, allowing for efficient energy transfer. Transformers are essential in electrical power distribution, enabling the transmission of electricity over long distances. By stepping up voltage for transmission and stepping it down for safe use in homes and businesses, transformers help minimize energy loss and ensure that electrical systems operate effectively.
