1 EE201 Linear Circuit Analysis I Lecture 3. Topics: passive sign convention, power conservation, resistance, Ohm’s Law. 1. Review of Passive Sign Convention Q. Why the name Passive Sign Convention? A. A “passive” circuit element is one that (on the average) must dissipate energy. So when P=VI is computed for a passive element, we would expect that P>0 if P = power absorbed. If labeled with the passive sign convention, such will happen for the passive circuit element. (Prof. Krogmeier, ECE) P AB = V AB x I AB = power absorbed by circuit element with terminals labeled A and B. Practice Problem 1. Given a two-terminal element, how many different ways can you mark the polarity of voltage and the direction of current? Of these, which one(s) follow the Passive Sign Convention? ( Feel free to discuss amongst yourselves .)

2 Practice Problem 2. Compute power absorbed (or dissipated ) by elements #1, #2, #3. Of the three elements, which element(s) could be the source(s)?
