Z1=10-j•2ом,z2=8ом,z3=-5+j•3ом

It looks like you have provided three different complex impedance values - Z1, Z2, and Z3. Complex impedance is often used in electrical engineering to represent the opposition of a circuit element to the flow of an alternating current.

Here are the given complex impedance values: Z1 = 10 - j2 Ω Z2 = 8 Ω Z3 = -5 + j3 Ω

If you have any specific questions or if you need help with calculations or concepts related to these complex impedances, please let me know.
