Step 1
Step 1: The average power absorbed by a load is given by: $$P_{avg} = \frac{1}{2} |V|^2 \frac{R}{|Z|^2}$$ where: * $V$ is the voltage across the load * $R$ is the real part of the load impedance * $|Z|$ is the magnitude of the load impedance Show more…

Calculate the average power absorbed by an impedance Z = (30 - j70) Ω when a voltage V = 120∠0° is applied across it.

If $[\mathbf{z}]=\left[\begin{array}{ll}50 & 10 \\ 30 & 20\end{array}\right] \Omega$ in the two-port of Fig. 18.72 calculate the average power delivered to the $100-\Omega$ resistor.
A practical voltage source is modeled by an ideal voltage source V with an open-circuited effective value of 320V in series with an output impedance Zg = 50+j100. The source feeds a load Z = 200+j100. See Fig. 10-30. Find the average power and reactive power delivered by V when added in parallel to Z. Find the X such that power delivered to Z is maximized.
