Document Summary
07(ba2159 f11-12) ( 1 point for incorrect tutorial section information) Test 1 answer all questions (non-programmable calculators allowed) 1, the power absorbed by the load resistance rl (in the dashed box) is 5. 38 milliwatts: find the current through the load resistance irl. Irl = 1. 64 ma: find the current through the load resistance due to the 12v voltage source only, i. e. , in the absence of the current source. Solve for irl-1 using any method (2 point). Solve for ix using any method (2 point): using the superposition method, find the value of the current source ix [4 points] To maximize the power to rl, then rl must be equal to the thevenin resistance as seen between the terminals of rl, i. e. , the equivalent resistance between terminals. A and b after deactivating all the sources. Question 2 [10 points: for the circuit shown in fig. 2, use a sequence of source transformations to find the current io [6 points]
