Phasor diagram (complex plane) with the y-axis as imaginary part and x-axis as real part of a complex number. As an example, the complex resistance of a coil \( Z_{\text L} = i \, \omega \, L \) (complex part only), the ohmic resistance \( Z_{\text R} = R \) and the complex resistance of a capacitor \( Z_{\text C} = -\frac{i}{\omega \, C} \) are shown. Vector addition of the three complex numbers yields the complex total resistance \(Z\).
