A varistor is an electronic component with a nonlinear current–voltage characteristic, and is therefore also known as a voltage-dependent resistor (VDR). The response curve of a varistor is similar to a diode. In contrast to a diode however, it has the same characteristic for both directions of traversing current. At low voltage it has a high el...

varistor In electricity, a variable resistor. A two-electrode resistor made of semiconductor material and having voltage-dependent nonlinear resistance which drops with an increase in applied voltage; can be used to protect sensitive equipment from power spikes or lightning strikes by shunting the energy to the ground.
