A galvanometer of resistance ' G ' is shunted by resistance of 'S' ohm. To keep the main current in the circuit unchanged the resistance to be put in series with Galvanometer is

Options

  1. AG ^2 ~S + G
  2. BG S + G
  3. CS ^2 G + S
  4. DGS S + G

Correct answer

A. G ^2 ~S + G

Step-by-step solution

array ll & Now, G = ( GS S + G )+ S ^ & G - GS S + G = S ^ & S ^ = G ^2 ~S + G array
