Given the equivalent impedance of a circuit can be calculated by the expression
If Z 1= 4 + j10 and Z 2= 12 - j3,
(a) calculate the impedance Z in both rectangular and polar forms.
(b) Three impedances are connected in parallel, Z 1= 2 + j2,
Z 2= 1 + j5 and Z 3= j6. Find the equivalent admittance Y.
where:
Express the admittance in both rectangular and polar forms.
