Answer:
The formula for Impedance for circuit with R, C, and L are:
![z=\sqrt{R^{2}+\left ( \omega L-\frac{1}{\omega C} \right )^2}](https://tex.z-dn.net/?f=z%3D%5Csqrt%7BR%5E%7B2%7D%2B%5Cleft%20%28%20%5Comega%20L-%5Cfrac%7B1%7D%7B%5Comega%20C%7D%20%5Cright%20%29%5E2%7D)
The impedance Z of the series RLC circuit depend upon angular frequency ω. Impedance is measured in ohms and resistance (R), inductance reactance and capacitive reactance. Series RLC circuit consist of the resistance, a capacitance and an inductance connected in the circuits. Electrical impedance is the measurement of the opposition that a circuit present in a current.
