For the following RC circuit with a DC voltage source. Initially the switch has been opened for a long time.
At t=0, the switch closed.
1. Find the expression for Vc(t) for t>0 and sketch Vc(t) for 1>t>-1
2. Determine the value of time t for which Vc(t) is 8V.
3. What is the amount of stored energy in capacitor at t=0.1sec
.
