Show answer and explanation Correct answer: (A) P–L,Q–K,R–N,S–M
Explanation Maxwell bridge suits medium-Q inductance, P–L. Kelvin double bridge reduces lead/contact errors in low-resistance measurement, Q–K. Hay bridge suits high-Q inductors, R–N. Schering bridge measures capacitance and dielectric loss, S–M. Thus A.
