Varistors are______________?
Correct answer: B. non-linear resistors
- A. insulators
- B. non-linear resistors
- C. carbon resistors
- D. resistors with zero temperature coefficient
Explanation
A varistor is a voltage-dependent resistor whose resistance changes nonlinearly with applied voltage. It is commonly used for surge suppression, so it is not an ordinary fixed carbon resistor.
