This is Part 1 of Assignment 6.
Question 1
Consider the following circuit composed of a network of resistors:
Question 2
Referring to the circuit shown below, what value of $ R_L $ (in terms of $ R_1 $ and $ R_2 $) will result in the maximum power being dissipated in the load? |
Hint: this is much easier to do if you first remove the load, and calculate the equivalent Thevenin output resistance $ R_T $ of the divider looking into the node labeled $ V_{out} $ (the Electronics primer has a section on Thevenin Equivalent circuits). Then express $ R_L $ for maximal power transfer in terms of $ R_T $.
Question 3
In the following circuit, R = 10 kΩ and C = 10 nF.
Note: You may find the pages on Impedance Analysis and Transfer Functions and Bode Plots helpful for this problem.
