WarmUp questions are worth 5 points each towards your "Homework and Web Assignments" score (250 points total).




1.

The voltage across a capacitor is given by the formula V=Q/C, where Q is usually called "the charge on the capacitor." Where is this charge in a capacitor? Does the capacitor really have a net charge? If two capacitors are connected together is the charge on one the same as on the other?





2.

You and a close friend stand facing each other. You are as close as you can get without actually touching. If a wire is attached to each of you, you can act as the two conductors in a capacitor. Estimate the capacitance of this "human capacitor".





3.

What is the relationship between the charges on the electrodes of a cylindrical capacitor?

Larger on the outer cylinder.

Larger on the inner cylinder

Exactly the same.

Equal in magnitude but opposite in sign

Any relationship is possible.
