The three impedances Z1= 20∠30, Z2= 40∠60, Z3= 10∠-90 are ...
Ω, Z2= 30 Ω, and Z3= 40 Ω are connected in series.
To find the total impedance, we simply add the individual impedances together:
Total impedance = Z1 + Z2 + Z3
Total impedance = 20 Ω + 30 Ω + 40 Ω
Total impedance = 90 Ω
Therefore, the total impedance of the three impedances connected in series is 90 Ω.
To find the total impedance, we simply add the individual impedances together:
Total impedance = Z1 + Z2 + Z3
Total impedance = 20 Ω + 30 Ω + 40 Ω
Total impedance = 90 Ω
Therefore, the total impedance of the three impedances connected in series is 90 Ω.
