Formula used:

The charge on capacitor at time t, when the switch is closed is

Where Q is the Charge

is the emf

T is the Time period

R is the Resistance

C is the Capacitance

At t=0, the charge on the capacitor is

After a long time , the charge on the capacitor is

The current in inductor L is given by

Where I is the current

is the voltage or potential difference

R is the Resistance

L is the inductance

T is the time period

At initial we take, t=0, the current in the inductor is given by

After a long time = is

The charge on C long after t=0 is

The current in L long after t = t₀ is
