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.

Is this formula applicable for RL circuit also?

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).

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.
