Whether Kirchoff's Law Is Applicable In A/c.then Say How

using impedance/reactance

V=I|Z|

where Z is

|Z|=\sqrt{R^2+ \chi ^2}

where \chi is

\chi = \chi _L - \chi _C

where \chi _L and \chi _C are

\chi _L=2 \pi f L and \chi _c= \frac{1}{2 \pi f C}

note: these equations only give you maximum or rms voltage or current

for instantaneous use these, which if you don't know, are sinusoidal functions

\tilde{V} = V_0e^{i(\omega t + \phi_V)}

and

\tilde{I} = I_0e^{i(\omega t + \phi_I)}

\omega = 2 \pi f and tan( \phi ) = \frac{ \chi}{R}

It is very much applicable. The catch is that you should have them in complex form (phase and magnitude) and all listed currents and voltage must be of the same frequency.
