Question
A capacitor of capacitance C is charged to a constant potential difference V and then connected in series with an open key and a pure resistor R. At time t = 0, the key is closed. If I is the current at time t, a plot of log I against t is shown as (1) in the graph. Later one of the parameters, i.e., V, R and C is changed, keeping the other twoconstant and graph (2) is recorded. Then :-
Options
A.C is reduced
B.C is increased
C.R is reduced
D.R is increased
