Question

22) Let V123 = the 1st three non-zero digits of your StudentID in volts and 1789 = the last 3 non-zero digits of your StudentID in mA in Circuit 1. For example, if your StudentID is 2302613, then V123 = 232V, and 1789 = 613 mA. Replace R1 by the first digit of your StudentID (in k22), R2 by the second digit (in k92), etc. If you have a 0 digit in your StudentID, use 10 k 2 instead of 0 k 2. For example, if your StudentID is 2302613, then R1 = 2 k22, R2 = 3 k22, R3 = 10 k 2, etc. 486uA R1 1789 5k R3 I R2 R5 5K co 4k R4 551V V123 RL A) (4 points) Hand Analysis: Analyze Circuit 1 by hand in order to determine the value of RL such that maximum power is delivered to RL and to determine the value of maximum power that is delivered to RL. B) (4 points) PSPICE Analysis: Use PSPICE to analyze Circuit 1 where RL varies from 0.1 RTh to 10RTH using the value of RTh determined in step A. Use at least 50 points per decade in the analysis. Plot PL vs RL with RL on a log scale using PROBE (you can plot the function VL*VL/RL). Place a cursor on the maximum point on this graph (use the PEAK function in PROBE) and mark the point. This point will correspond to Rth and Pmax. Always add the following text to the graphs in PSPICE: Name, Course, PSPICE Assignment Number, Problem Number, and the Purpose of the Analysis. C) (2 points) Discussion: Compare the values of Rth and Pmax determined in steps A and B in a table and discuss the results.
