The galvanometer shown in the figure has resistance 10 . It is shunted by a series combination of a resistance S=1 and an ideal cell of emf 2 V. A current 2A passes as shown. Then choose the correct statement(s).

Options

  1. AThe reading of the galvanometer is 1 A
  2. BThe reading of the galvanometer is zero
  3. CThe potential difference across the resistance S is 1.5 V
  4. DThe potential difference across the resistance S is 2 V

Correct answer

D. The potential difference across the resistance S is 2 V

Step-by-step solution

In loop ABCDA 10 i+2-(2-i)=0i=0 Potential difference across S (2- i ) 1=2 ~V
