Various types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, a

In an electric arc furnace, the transformer has a heavy copper bus for the low voltage winding, which can be rated for tens of thousands of amperes. Winding beginnings and ends are led out separately and "interleaved" for the external delta closure in a Knapsack connection. The transformers are immersed in oil for cooling and insulation, and are designed to withstand frequent short circuits.

Homemade Tesla coil in operation, showing brush discharges from the toroid. The high electric field causes the air around the high-voltage terminal to ionize and conduct electricity, allowing electricity to leak into the air in colorful corona discharges, brush discharges and streamer arcs. Tesla coils are used for entertainment at science museums and public events, and for special effects in movies and television.
Unipolar coil design widely used in modern coils. The primary is the flat red spiral winding at bottom, the secondary is the vertical cylindrical coil
Unipolar coil design widely used in modern coils. The primary is the flat red spiral winding at bottom, the secondary is the vertical cylindrical coil wound with fine red wire. The high-voltage terminal is the aluminum torus at the top of the secondary coil.

Bipolar coil, used in the early 20th century. There are two high-voltage output terminals, each connected to one end of the secondary, with a spark gap between them. The primary is 12 turns of heavy wire, which is located at the midpoint of the secondary to discourage arcs between the coils.
