Answer any twofull questions, each carries10 marks.
A series RLC circuit consists of a resistance 20 Q, inductance 0.05H and (10)
capacitance 20uF in series with a 100 V constant voltage source when the switch
is closed at 1-0. Find the expression for the current in the circuit. Also find the
current at t=3ms.
In the given circuit shown in fig.(7), the switch is closed to position 1 at ٠ and (10)
after a time equal to one time constant it is moved to position 2. Find the
expression for current after moving to position 2. Assume zero initial charge on
the capacitor.
(Use Laplace transform technique)
