Question

An M.I meter has a resistance of 0.5 ohm and
reads 0.1A at full scale. It is intended to convert it
into an ammeter to read 0.5A. The modification
needed is to
1) connect a shunt of 0.01 ohm
2) connect series resistance of 0.01 ohm
3) connect a shunt of 0.0102ohm and a series
resistance 0.0102 ohm
4) connect a shunt of 0.0102 ohm.​
