Objective 2-Understand the condition for maximum real power delivered to a load in an ac circuit
10.7 The source current in the circuit shown is
3.6 mH
3 cos 5000t A.
a) What impedance should be connected
across terminals a,b for maximum average
power transfer?
b) What is the average power transferred to
the impedance in (a)?
c) Assume that the load is restricted to pure
resistance. What size resistor connected
$200
5 µF
4Ω
Answer: (a) 20 – j10 N;
(b) 18 W;
across a,b will result in the maximum aver-
(c) 22.36 N;
age power transferred?
(d) 17.00 W.
d) What is the average power transferred to
the resistor in (c)?
NOTE: Also try Chapter Problems 10.41, 10.48, and 10.62.
