Circuit Theory/Complex Power/complex conjugate

The quantity $$\mathbb{I}^*$$ denotes the complex conjugate of the phasor current. To get the complex conjugate of $$\mathbb{I}$$, we have two formulas:

Given: $$\mathbb{I} = A + jB = M \angle \phi$$


 * $$\mathbb{I}^* = A - jB$$ (rectangular)
 * $$\mathbb{I}^* = M \angle -\phi$$ (polar)

There is more information on complex conjugation of phasors in the Appendix.
