I think from the phasor diagram, inductance Voltage (VL) is opposite capacitance-voltage (Vc). Therefore, if the circuit includes VR, Vc, and VL, the resultant Vrms will be sqrt (Vr^2 + (Vc - VL)^2).

In series circuit voltage is add/subtract with their polarity.
Vrms = Sqrt(Vc^2+Vr^2).
Where & how from this formula comes?
Vrms = Sqrt(Vc^2+Vr^2).

For everyone using the "Vrms = Sqrt(Vc^2+Vr^2)" equation, what is your source? I have never seen this equation before.

To find the rms value of RC series circuit the formula is
Vrms^2= Vr^2+Vc^2
Vrms= square root of( Vr^2+Vc^2)
Vrms^2= Vr^2+Vc^2
Vrms= square root of( Vr^2+Vc^2)

Vrms = (V1+V2)/1.404.
= (12+15)/1.404.
= 27/1.404 = 19.23 Answer.
= (12+15)/1.404.
= 27/1.404 = 19.23 Answer.

Vrms^2 = 12^2+15^2 = 369.
Vrms^2 = 369.
Vrms = Root under 369.
Vrms = 19.20.
Vrms^2 = 369.
Vrms = Root under 369.
Vrms = 19.20.

What is the correct formula of V(rms) for rc series and parallel circuit?
Kiran said:

Vrms = sqrt of vr^2+vxc^2
= sqrt of 12^2+15^2
= 19.2v
= sqrt of 12^2+15^2
= 19.2v

Is this formula applicable for RL circuit also?
