In an ammeter 0.2% of main current passes through the galvanometer. If resistance of galvanometer is G, the resistance of ammeter will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Here, resistance of the galvanometer 
Current through the galvanometer,
∴ Current through the shunt,
As shunt and galvanometer are in parallel
Resistance of the ammeter 
is
