A voltmeter of resistance 998 is connected across a cell of emf 2 V and internal resistance 2 . The potential difference across the voltmeter is

Options

  1. A1.99 V
  2. B3.5 V
  3. C5 V
  4. D6 V

Correct answer

A. 1.99 V

Step-by-step solution

From Ohm's law i= E R+r = 2 998+2 =2 10⁻³ ~A Potential difference across the voltmeter is V=i R= (2 10⁻³ ) 998=1.996 ~V
