The residing of the voltmeter is. (A) (10/3)V (B) 5V (C) (20/3)V

Question

An electrical circuit is shown in fig the values of resistances and the directions of the currents are shown A voltmeter of resistance 400Ω is connected across the 400Ω resistor. The battery has negligible internal resistance.

The residing of the voltmeter is. 

(A) (10/3)V

(B) 5V

(C) (20/3)V

(D) 4V

Answer 1

The correct option (C) (20/3)V   

Explanation:

reading of voltmeter = I × R
voltmeter is across branch BC, hence reading = 200 × I₂ 

= 200 × (1/30) = (20/3)V = 6.67volt
