|RMS source voltage=sqrt(12^2+15^2)=19.2v|
|Ponrajan said: (Mar 11, 2012)|
|What is the formula to find rms value?|
|Poovizhi said: (May 18, 2012)|
|To find the rms value of RC series circuit the formula is
Vrms= square root of( Vr^2+Vc^2)

|Kiran said: (Dec 2, 2012)|
|Vrms = sqrt of vr^2+vxc^2
= sqrt of 12^2+15^2
|Sanjeev Singh said: (Jul 21, 2013)|
|Vrms = square root of( Vr^2+Vc^2)?|
|Suji said: (Mar 1, 2014)|
|Please anyone give the correct solution for this problem.|

|What is the correct formula of V(rms) for rc series and parallel circuit?|
|Koti said: (Jul 4, 2014)|
|In series circuit voltage is add/subtract with their polarity.
Vrms = Sqrt(Vc^2+Vr^2).
Where & how from this formula comes?
|Vasiq said: (Jan 17, 2015)|
|For everyone using the "Vrms = Sqrt(Vc^2+Vr^2)" equation, what is your source? I have never seen this equation before.|
|Nikku Kumar said: (Mar 1, 2015)|
|Vrms^2 = 12^2+15^2 = 369.
Vrms^2 = 369.
Vrms = Root under 369.
Vrms = 19.20.

|Is this formula applicable for RL circuit also?|
|Sunny said: (Sep 10, 2015)|
|If L is include then what is Vrms=?|
|Gozie said: (Oct 14, 2016)|
|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).|

|Sqrt of 12^2+15^2 = 19.2.|
