Question

A, B and C are voltmeters of resistances R, 1.5R and 3R respectively. When some potential difference is applied between X and Y, the voltmeter readings are V_A, V_B and V_C respectively.

(a) V_A = V_B = V_C 

(b) V_A ≠ V_B = V_C 

(c) V_A = V_B ≠ V_C 

(d) V_B ≠ V_A = V_C

Answer 1

Correct Answer is: (a) V_A = V_B = V_C 

V_A = iR  

V_B = 2i/3 (1.5R) = iR  

V_C = (i/3) (3R) = iR.
