Abstract
Simple harmonic motions are motions that are described mathematically with the use of cosine functions.
This experiment will attempt to intimidate simple harmonic motions

Loop rule
Vloop = 0
The total change in voltage as you go around a closed loop
must be zero, (i.e. you end up where you started from).
Junction rule
Iin = Iout
The total current into a junction must equal the total charge
out of the junction. (i.e. charge
Section 24-3: Capacitors, Batteries, and Circuits
Wires are conductors, which we usually treat as ideal. An ideal conductor allows charge to
move freely, and because of this an ideal conductor has no voltage drop along it. An ideal
conductor behaves the s
21-4: The Electric Field
An electric field is caused by a distribution of charges. The field exists
everywhere, but only exerts a force when a charge is placed in the
field.
When a test charge is placed in an electric field, it feels a force F due to the

Capacitance is a measure of a conductors capacity to store charge Q at a voltage V.

Units of farad = coulomb per volt, F = C/V
Since V is always proportional to Q, the capacitance is independent of e
