EE 200: In-Class Exercises

1. What is the Thevenin model, and why is it useful?

2. How might you determine a Thevenin equivalent model for a solar cell from experimental measurements? Describe the steps you would perform.

3. Consider an audio amplifier that can be modeled by a Thevenin circuit with a resistance of . Suppose the maximum voltage the amplifier can produce is V.
   1. What is the peak power that is delivered to one 8 speaker connected to the amplifier, as shown below?

   2. Suppose that two speakers are to be driven by this amplifier. The speakers can be connected in series or in parallel, as shown below. How much power is delivered to each speaker in the series connection? What about the parallel connection? Which connection is ``better''?
