Varistors are mainly used for transient overvoltage protection, but their volt-ampere characteristics are similar to those of semiconductor voltage-regulators, and enable it to have a variety of circuit element functions, such as:

1. DC high voltage small current voltage stabilizer, its stable voltage can be as high as several kilowatts, this is silicon voltage regulator can not achieve. 

2. voltage fluctuation detection element.

3. DC battery shift element. 4.voltage equalizing elements.5. fluorescent starting elements.

Voltage sensitive resistor is a kind of voltage limiting protection device. When overvoltage occurs between the two poles of the varistor, the voltage clamp can be positioned to a relative fixed voltage value to realize the protection of the back stage circuit.
