An ammeter measures the current passing through a circuit. In this case, a galvanometer with resistance G is used as part of the ammeter setup. When 5% of the main current passes through the galvanometer, we need to find the resistance of the ammeter.
What will be the resistance of the ammeter if the resistance of the galvanometer is G?
a) 0.05G
b) 0.95G
c) 20G
d) 19G
