Current, voltage, and impedance in an RLC circuit are related by an AC version of Ohm's law: I0=V0Z or Irms=VrmsZ I 0 = V 0 Z or I rms = V rms Z .

How do you calculate RMS current in RLC circuit?
RLC Series Impedance
For an applied rms voltage V = volts, the rms current will be I = x 10^ amperes. The component voltages can be obtained by multiplying the current times the component impedances. Capacitor: VC = IXC = volts.
What is RLC circuit formula?
RLC circuit equations that give the impedance measured in volts and phase measured in degrees are: Z=√R2+(XL−XC)2=√R2+(ω∗L−1ω∗C)2 Z = R 2 + ( X L − X C ) 2 = R 2 + ( ω ∗ L − 1 ω ∗ C ) 2 .
How do you find the current in a LCR circuit?
If XL > Xc, then tan θ > 0 and the voltage leads the current and the circuit is said to be inductive. If XL < Xc , then tan θ < 0 and the voltage lags the current and the circuit is said to be capacitive. If XL = Xc , then tan θ = 0 and the voltage is in phase with the current and is known as resonant circuit.
