Circuit Theory/Complex Power/complex conjugate

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

Given: $𝕀=A+jB=M\mathrm{\angle }\varphi$

• ${𝕀}^{*}=A-jB$ (rectangular)
• ${𝕀}^{*}=M\mathrm{\angle }-\varphi$ (polar)

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