When measuring insulation resistance of cables using d.c. source, the galvanometer used should be initially short circuited because
(A) Cables have a low value of capacitance which draws a high value of charging current
(B) Cables have a low value of initial resistance
(C) Cables have a high value of capacitance which draws a high value of charging current
(D) Cables have a low value of capacitance and initial resistance
(A) Cables have a low value of capacitance which draws a high value of charging current
(B) Cables have a low value of initial resistance
(C) Cables have a high value of capacitance which draws a high value of charging current
(D) Cables have a low value of capacitance and initial resistance
