How can R1 be scaled?

(a) by using a scale

(b) by using an ohmmeter

(c) by calibration

(d) by using a galvanometer

The question was posed to me at a job interview.

This key question is from Advantages and Limitations of Maxwell Bridge topic in section Measurement of Inductance and Capacitance of Electrical Measurements

Best answer
Right option is (c) by calibration

For explanation I would say: The resistance R1 in a Maxwell inductance capacitance bridge can be scaled through calibration. The value of the Quality factor Q can be read directly through calibration.
