I come accross the impedance for an inductor an capacitor combined is Z = XL - XC, for a resistor and capacitor in series is Z = sqrt(R^2 + XC^2) and how do you obtain a formula for a combination of a capacitor, an inductor and a resistor in series and in parallel?

2. Relevant equations

I come accross the impedance for an inductor an capacitor combined is Z = XL - XC, for a resistor and capacitor in series is Z = sqrt(R^2 + XC^2)

3. The attempt at a solution

in series, Z = R + wL + 1/(w*L)

in parallel Z = (R*wL)(1/wL)/(R+wL)+(1/wC)
