RC Circuits
Equations:
(1) C(Computer) = 1/RC
(2) Aexp(Ct) + B
(3) V(t) = V(0) exp (t/RC)
(4) V(t) = V(0)e

(5) q=CV
Theory:
Capacitors store charge. Equal and opposite charges placed on the two sides of the
capacitor and produce a voltage difference between the two sides of the capacitor.
When a capacitor is placed in series with a resistor R, the charges will move through
resistor in a direction to reduce the total charges on the capacitor. The charge will
decrease at a rapid rate, but as the stored charge decrease, the rate will decrease.
The time required to charge or discharge a capacitor place in series with a resistor can be
used to determine the end product of the resistance times the capacitance. Therefore,
knowing either the resistance or capacitance, we can find the other value.
Procedure:

Connect the volt outputs to the switch and to the side of the capacitor; with
resistor on the other side of the capacitor. Be sure that the power supply is off.
