Question

When shunt of 4 Ω is attached to a galvanometer, the deflection in the galvanometer is reduced to 1 5 th . If an additional shunt of 2 Ω is also connected. The deflection of galvanometer will be reduced to, 1 10 th of initial, 1 13 th of initial, remains the same, none of these

MARKS App · Accepted Answer

Intial condition When shunt of 4 Ω is used, i 5 × G = 4 5 i × 4 ⇒ G = 16 Ω When additional shunt of 2 Ω is attached, i ' × 16 = i − i ' 4 3 12 i ' = i − i ' ⇒ i ' = 1 13 It will reduce to 1 13 of the initial value.
