electronics
Quick Summary
A resistance dimmer is an adjustable resistor used to control the intensity of lights in an electric circuit. It was the first commercially successful theatrical dimmer, developed in the late 19th century. Resistance dimmers were portable, efficient, and rugged, and worked on both alternating and direct current.12
While effective, resistance dimmers have largely been replaced by electronic dimmers, such as silicon-controlled rectifier (SCR) dimmers, which offer more precise control and remote operation capabilities.2
