Question
Two identical galvanometers are taken, one is two be converted into an ammeter and other into a milliammeter, Shunt of milliammeter compared ammeter is
Options
A.less
B.more
C.zero
D.none
Solution
The Shunt of milliammeter will be of larger resistance, because a larger part of the main current will pass through pass through the coil of the galvanometer which will work as a smaller range ammeter.
