Three voltmeters A , B and C having resistances R , 1.5 R and 3 R , respectively, are connected as shown. When some potential difference is applied between X and Y , the voltmeter readings are V _ A , V _ B and V _ C respectively. Then -

Options

  1. AV_ A V_ B =V_ C
  2. BV_ A =V_ B V_ C
  3. CV _ A V _ B V _ C
  4. DV_ A =V_ B =V_ C

Correct answer

D. V_ A =V_ B =V_ C

Step-by-step solution

V_ A =I RV_ B = ( 2 I 3 ) 1.5 R=I R V_ C = ( 1 3 ) 3 R=I R V_ A =V_ B =V_ C
