Capacitor Charge and Discharge
This experiment will involve charging and discharging a capacitor, and using the data recorded to calculate the capacitance of the capacitor. It''s important to note that a large resistance resistor (such as a 10 : text{kΩ} resistor) is used to allow the discharge to be slow enough to measure readings at suitable time intervals.
Simple Equation for Capacitor Charging With RC Circuits
In order to charge a capacitor with the simplest method, we will use a capacitor (C), a resistor (R), and a DC voltage source. We connect these components all in series with the addition of a switch. At the initial time, or time zero, the switch is closed and the capacitor is starting to charge up.

Capacitance and Charge
For circuits containing resistance and a capacitor in series, an important numerical value is the RC product, often specifically denoted by Ƭ (tau). The RC product of the circuit is known as the time constant and is the time required for the voltage on the capacitor to rise to approximately two-thirds of its final value or to decay to one-third of …
