Q2:
The circuit shown in Fig.- 2
quency of 10 krad/s. Assume a is rcal and lics
between -50 and + 50, that is,-50 s as 50.
is operating at a fre-
a so
a) Find the value of a so that the Thévenin imped-
ance looking into the terminals a,b is purely
resistive.
b) What is the value of the Thévenin impedance for
the a found in (a)?
c) Can a be adjusted so that the Thévenin
impedance equals 5 + js N? If so, what is the
value of a?
d) For what values of a will the Thévenin imped-
ance be inductive?
