Maximum power transfer theorem

A resistive load will consume maximum power from a network when the load resistance is equal to the resistance of the network as viewed from the open-circuit terminals, with all energy sources removed leaving only the internal resistances. Physicist Mori…

Textbook Question

Chapter 2, Problem 2.25P

Consider the series RLC circuit of Problem 2.7 and calculate the complex power absorbed by each of the R, L, and C elements, as well as the complex power absorbed by the total load. Draw the resultant power tna ngle. Check whether the complex power delivered by the source equals the total complex power absorbed by the load.

"Can you explain the integration method to show the result?" The radiation intensity of an aperture antenna, mounted on an infinite ground plane with perpendicular to the aperture, is rotationally symmetric (not a function of 4), and it is given by U = π sin Find the approximate directivity (dimensionless and in dB) using (a) numerical integration. Use the DIRECTIVITY computer program at the end of this chapter. U sin ( sin ) sin (a) Directly Do = 14.0707 = 10log (14.0707) = 11.48 dB
