Determine the admittance (in rectangular form) of (a) an impedance Z = 1000 + j400 ; (b)

QUESTION:

Determine the admittance (in rectangular form) of (a) an impedance \(Z = 1000 + j400\ \Omega\); (b) a network consisting of the parallel combination of an \(800\ \Omega\) resistor, a 1 mH inductor, and a 2 nF capacitor, if \(\omega = 1\ Mrad/s\); (c) a network consisting of the series combination of an \(800\ \Omega\) resistor, a 1 mH inductor, and a 2 nF capacitor, if \(\omega = 1\ Mrad/s\).
