A) high resistance in series
B) low resistance in parallel
C) high resistance in parallel
D) low resistance in series.
Correct Answer: A
Solution :
Let G be the resistance of the galvanometer and \[{{i}_{g}}\]the current, which on passing through the galvanometer, produces full-scale deflection. Suppose V is the maximum potential difference to be measured which exists between points a and b. On connecting the galvanometer across a and b a current \[{{i}_{g}}\] flows through it. Then from Ohm's law we have.You need to login to perform this action.
