Only 4 % of the total current in the circuit passes through a galvanometer. If the resistance of the galvanometer is G, then the shunt resistance connected to the galvanometer is

Answer: (B)

Solution

Let the total current be . The galvanometer current is , so the shunt carries . The galvanometer and shunt are in parallel, so , giving , option (b). Option (a)
