tricks to solve RC circuit questions
Any circuit U can easily identify and solve through their respective Phasor diagrams.
The thing is that U must know hoq to draw their phasor diagrams, after then U have solved 90% of the proble.
Here U are asking about RC circuit,
In RC circuit U must know or learn that capacitance lacks behind with Irms BY A PHASE of 90''.
See below:
Now if U want to find Vrms THEN IT IS EQUAL TO net V given above.
Now u can find. through this.

In the RC circuit shown below, the switch is closed on position 1 at t = 0 and after 1 τ is movedto position 2. Find the completecurrent transient.
Suppose you should choose a circuit as i given here...
?
For ant R , L , C Circuit ; We have simplified formula that
v / i at any time t :
v ( t ) = v_final - { v_final - v_initial } * ext ( t / time contsant)
i ( t ) = i_final - { i_final - i_initial } * ext ( t / time contsant)
here v_final / i_final = Value of v or i at Steady state(infinity) condition .
v_initial / i_initial = Value of v or i at 0+ condition .
