A moving coil galvanometer of resistance 
is used as an ammeter using a resistance 
. The maximum deflection current in the galvanometer is 
. Find the minimum current in the circuit, so that ammeter shows maximum deflection?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Here 
and 
are parallel to each other hence both will have equal potential difference.
So, circuit current is 
.
