Let the voltage and current in an element be \(V = V_m \angle \theta_V\) and \(I = I_m \angle \theta_I\). The complex power delivered to the element is defined as:

\(S = \frac{V_mI_m}{2} \angle(\theta_V - \theta_I)\)

\(S = V_m I_m \angle (\theta_V - \theta_I)\)

\(S = \frac{V_mI_m}{2} \ \angle (\theta_I-\theta_V)\)

Let the voltage and current in an element be \(V = V_m \angle \theta_
