The experiment used single and double capacitor circuits to measure current over time. Graphs of the data were used to calculate the time constants and capacitances. The time constant for the single capacitor was determined to be -3.279 s and the capacitance was calculated to be -3.279 x 10-4 F.
The simplest form of a capacitor consists of two parallel conducting plates, each with area A , separated by a distance d. The charge is uniformly distributed on the surface of the plates. The capacitance of the parallel-plate capacitor is given by:
The capacitance of the device is defined as the amount of charge Q stored in each conductor after a potential difference V is applied: The simplest form of a capacitor consists of two parallel conducting plates, each with area A , separated by a distance d. The charge is uniformly distributed on the surface of the plates.
For the double capacitor, the time constant was -6.135 s and the capacitance was -6.135 x 10-4 F. The objectives of determining time constants and capacitances were achieved through quantitative analysis of experimental data.
The capacitance of the parallel-plate capacitor is given by: Where κ is the dielectric constant of the insulating material between the plates (κ = 1 for a vacuum; other values are measured experimentally and can be found in tables), and εo is the permittivity constant, of universal value εo = 8 x 10-12 F/m.
If capacitor can store one coulomb of electrical charge by applying one volt from a power source, it is said to have a capacitance of one “Farad”. For most electronic circuits, one farad of charge is too much. Capacitors are therefore frequently available in much lower capacitance values. A. Single Capacitor 1.

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful …
