Input Impedance Z
Let R = Resitance = 100 Ohms
L = Inductance = 1 mH
C = Capacitance = 1 uF
Inductive impedance of L = jwL
Capacitive impedance of C = (1/jwC)
R and C are in parallel; hence the effective impedance of this combination is:
[ (R*jwC)/(R+jwC)]; this is then in seried with L.
So, Input Impedance = Zin = jwL + [ ...
