How does a power transformer work?

A transformer takes in electricity at a higher voltage and lets it run through lots of coils wound around an iron core. Because the current is alternating, the magnetism in the core is also alternating. Also around the core is an output wire with fewer coils. read more

A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it. read more

A transformer is the inseparable part of a power system. Proper functioning of transmission and distribution systems is not possible without the transformer. For the stable operation of the power system, the transformer should be available. read more
