Q1:

When a current source I is suddenly connected across a two terminal relaxed RC circuit at time t = 0, the voltage across the current source is shown in figure. The RC circuit is

A a series combination of R and C

B a parallel combination of R and C

C a series combination of R and parallel combination of R and C

D a pure capacitor

ANS:C - a series combination of R and parallel combination of R and C

Initially capacitor behaves as short-circuit and finally as open circuit.
