A circuit is so formed such that the source-R-C-diode-switch are in series.
Consider the initial voltage across the C to be zero.
The diode is so connected that it is forward biased when the switch is closed.
When the switch is closed,
A. the current will decay exponentially & the voltage will increase exponentially
B. the current will increase exponentially & the voltage will increase exponentially
C. the current will fall to zero & the voltage both will decay exponentially
D. the voltage and current both remain constant
