Question

What is the effect of breakdown of high voltage capacitor?

(a) No effect

(b) voltage drop across the circuit reduces

(c) circuit components rupture

(d) a high voltage appears across the branches

The question was posed to me in an online quiz.

This interesting question is from High Voltage Schering Bridge topic in division Measurement of Inductance and Capacitance of Electrical Measurements

Answer 1

Right option is (d) a high voltage appears across the branches

The best explanation: In a high voltage Schering bridge, a very high voltage appears across the branches when the breakdown of high voltage capacitor occurs. This is prevented by making use of a spark gap across the branches involved.
