While testing cables the galvanometer used should be initially short-circuited in order to protect it from sudden initial inrush currents as the cable have:
A)a low value of initial resistance
B)a low value of initial capacitance
C)a high value of initial capacitance
D)both (a) and (b)

Question

Quizplus · Accepted Answer

Cables have a high value of initial capacitance, which can cause a significant inrush current when testing begins. Short-circuiting the galvanometer protects it from this sudden surge.
