What is a varistor?<end_of_turn>
<start_of_turn>model
A varistor is an electronic component with a characteristic curve similar to that of the diode. The term comes from the contraction of the English variable resistor. Varistors are often used to protect circuits against voltage variations by incorporating them into the circuit so that when the varistor activates, current does not pass through sensitive components. A varistor is also known as a Voltage Dependent Resistor or VDR. The function of the varistor is to conduct a significant current when the voltage is excessive.<end_of_turn><eos>
