Urgent!! About Impedance

the total ohm of this impedance ( 30+j40 ) is 50ohm.
but wat is the conjugate impedance ?? 30-j40? total ohm is wat?

30+j40 is 50ohm
solution is square root of (302+402)

Hi KnightMars! Welcome to PF! :smile:

Yes, the complex conjugate of 30 + 40 j is 30 - 40j.

(you simply replace j by -j)

The magnitude of the complex conjugate impedance is always the same as the magnitude of the original impedance (in this case, 50 Ω). :wink:
