Question: (a) Given the equivalent impedance of a circuit can be calculated bythe expression
Z Z 1 Z 2
Z 1 Z 2
If Z 1 = 4 + j 10 and Z 2 = 12 – j 3, calculate the impedance Z in both rectangular and polar forms.
(b) Three impedances are connected in parallel, Z 1 = 2 + j 2,
Z 2 = 1 + j 5 and Z 3 = j 6. Find the equivalent admittance Y .
where:
Y

Z 1
1
1
Z 2 Z 3
Express the admittance in both rectangular and polar forms.
