Example of a voltage clamping device______________?
Correct answer: C. metal oxide varistor
- A. fast acting fuse
- B. snubber circuit
- C. metal oxide varistor
- D. aluminium block
Explanation
A metal-oxide varistor, or MOV, is a voltage-dependent resistor that remains high-impedance normally and conducts strongly during a voltage surge. A snubber limits switching transients but is not itself normally classified as a clamping device.
