Problem 31.10

Please wait for the animation to completely load.

Assume an ideal power supply.  The voltage of the source is the red plot on the graph.  Restart.

  1. Which plot shows the voltage across resistor A?
  2. Which is the voltage across resistor B? 

This is a basic design of a loudspeaker system in which the resistors represent speakers: a tweeter and a woofer.  The woofer, a large speaker, wants low-frequency signals (and generates low-pitched sound), while the tweeter, the small-diameter speaker, should get high-frequency signals (to generate high-pitched sound). 

  1. Which resistor represents the tweeter and which represents the woofer?  Explain.
