A series RC circuit has R=10Q and C=1F. If the circuit is connected to a 10V
DC supply at time t=0, determine (i) the time at which the voltage across the
capacitor is 59 and (ii) the circuit current at that instant.

The switch K in the circuit given below has been at position 1 for a long time.
Att=0, the switch is moved to position 2. Determine the current flowing
through the 1Q resistance for t 2 0 using Laplace transform technique.
