Question

Q Meter is used to measure _________

(a) Q factor of an inductive coil

(b) Only the effective resistance

(c) Only bandwidth

(d) Q factor of an inductive coil, the effective resistance, and bandwidth

This question was addressed to me during a job interview.

Asked question is from Advanced Problems on Q Meter topic in portion Electronic Instruments of Electrical Measurements

Answer 1

Correct answer is (d) Q factor of an inductive coil, the effective resistance, and bandwidth

To explain I would say: Q meter can measure the Q factor of an inductive coil. It can also measure the effective resistance. Also, the bandwidth can be measured by the Q Meter. Therefore it can be used for all the above functions.
