A moving coil galvanometer of resistance `100Omega` is used as an ammeter using a resistance `0.1Omega`. The maximum deflection current in the galvanometer is `100muA`. Find the minimum current in the circuit so that the ammeter shows maximum deflection.

A

100.1mA

B

1000.1mA

C

10.01mA

D

1.01mA

Text Solution
