Many devices use switches to control voltage and current. One of the most common switches and also one of the most efficient is the transistor. Much like a relay it can handle high current and is able to be controlled easily and fast. But the price of this speed is heat. The faster it is switched the hotter it will become. Cooling is only a stop-gap as transistors work much less efficiently when chilled below their operating range.
