Circuit Theorems in AC Analysis

Q1:

In order to get maximum power transfer from a capacitive source, the load must

A have a capacitive reactance equal to circuit resistance

B have an impedance that is the complex conjugate of the source impedance

C be as capacitive as it is inductive

D none of the above

ANS:B - have an impedance that is the complex conjugate of the source impedance

Maximum power transfer theorem for AC circuits that "maximum power is transferred to the load when the load is complex conjugate of the Thevnin's equivalent impedance".
