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 I_rms BY A PHASE of 90''.

See below:

Now if U want to find V_{rms 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 .
