MHT CET 2023 Physics question

If only 1% of total current is passed though a galvanometer of resistance 'G' then the resistance of the shunt is

(A)
(B)
(C)
(D)Correct

Answer: (D)

Solution

Let the total current be . The galvanometer carries , so the shunt carries . The shunt is in parallel with the galvanometer, so the potential differences are equal: $=(I-⇒
