Question

The application of a megger is _________

(a) to measure resistance

(b) to test for leakage

(c) to limit the current

(d) to increase the emf of the circuit

This question was posed to me during an interview.

My question is based upon Applications of Megger in division Measurement of Resistance of Electrical Measurements

Answer 1

Right option is (b) to test for leakage

To elaborate: Current flow through a circuit depends on the magnitude of the voltage source. Magnitude of the voltage source can be increased. A megger is mainly used for testing electrical leakages in wires.
