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