laplace rl circuit
When the switch is closed the inductor of 1 H and the capacitor are out of the circuit once the switch short circuit them.
When the switch opens, they sundenlly become part of the circuit.
In t(0-) the capacitor is completely discharged since the switch was closed for a long time, so the voltage across its terminals is 0 Volts, so in t(0+) the current through it should be maximum since it has no charge. On the other hand, the inductor offers a high oposition to rapid current variation, so at t(0+) it behaves like a open circuit and has all the voltage across its terminals, as consequence, the initial current acroos it is zero.
With this analisys you are able to set the initial conditions:
Vc(0+) = 0 and IL(0+)=0.
