1. (1 pt) In last week's homework we discussed using a 16-gauge wire to connect a stereo to an 8? speaker. Let's assume that the stereo supplies 20V across the wires at some instant.

a. If the resistance of the wire is 0.5?, what is the voltage drop in the wire and what is the voltage across the speaker?

b. If the resistance of the wire is 0.5?, what is the power dissipated in the wire and the power available to the speaker?

c. Answer questions a. and b. for the case when a long, thin wire having resistance of 2? is used.

2. (3 pts) A circuit consists of a battery and resistors arrayed as in the figure below.
