What is a Varistor? - A Galco TV Tech Tip | Galco
A varistor, also known as voltage-dependent resistor is an electronic component with a nonlinear varying resistance, dependent on the voltage applied. The impedance is high under nominal load conditions, but will sharply decrease to a low value when a voltage threshold, the breakdown voltage, is exceeded. They are often used to protect circuits ...
