Of the two identical galvanometers one is to be converted into an ammeter and another into a milliammeter. Which of the shunts will be of larger resistance?

Explanation

The shunt of milliammeter should have larger resistance. It is so because the current measuring range of milliammeter is less than that of ammeter. Therefore the larger potion of the main current must pass through galvanometer coil and less portion of current through shunt for a converted galvanometer into ammeter/milliammeter. It is only possible is the resistance of shunt used is of larger value in milliammeter than in ammeter.
