When it comes to amplification, the principal parameters are gain and fidelity of the output relative to the input. Gain, denoted by β (Greek letter beta), is the ratio of output voltage, current or power to input. An amplifier by definition has a power gain greater than one. Measurements that characterize amplifier gain serve as […]

The difference between testing thyristors and triacs
The thyristor is a two- or three-pin device comprised of four alternating P- and N- layers. It is also known as a silicon-controlled rectifier and is often used in light dimmer switches, speed controllers for electric motors, and switch gear for high-voltage dc power transmission systems. The thyristor does not function as an amplifier–its output […]
