Problem

A moving coil galvanometer of resistance

100\Omega

is used as an ammeter using a resistance

0.1\Omega

. The maximum deflection current in the galvanometer is

100\mu\text{A}

. Find the minimum current in the circuit so that the ammeter shows maximum deflection a.

100.1\text{mA}

1000.1\text{mA}

10.01\text{mA}

1.01\text{mA}
