Varistor is the abbreviation of voltage sensitive resistor, which is a nonlinear resistance element. The resistance value of the varistor is related to the voltage applied at both ends. When the voltage applied to the varistor is within its nominal value, the resistance value of the resistor is infinite and almost no current passes through. When the voltage at both ends of the varistor is slightly greater than the nominal voltage, the varistor will break down and conduct quickly, and its resistance value will drop quickly, making the resistor in the conduction state. When the voltage decreases below the nominal voltage, the resistance value starts to increase again, and the varistor returns to the high resistance state. When the voltage at both ends of the varistor exceeds its maximum limit voltage, it will be completely broken down and damaged and cannot be recovered by itself.
