Let the voltage and current in an element be \(V = V_r \angle \theta_V\) and \(I = I_r \angle \theta_I\). The complex power delivered to the element is defined as:
1
\(S = \frac{V_rI_r}{2} \angle(\theta_V - \theta_I)\)
2
\(S = V_r I_r \angle (\theta_V - \theta_I)\)
3
\(S = V_r I_r^*\)
4
\(S = \frac{V_rI_r}{2} \ \angle (\theta_I-\theta_V)\)
