For a capacitors are electronic the capacitance depends on the physical and geometrical proprieties of the device. It is given operationally by the ratio of the charge Q stored in the device and the voltage difference across the device ΔV. The schematic symbol of a capacitor is two parallel lines which represent the capacitor plates.
In this part of the lab you will be given 3 di erent capacitors, jumping wires, a breadboard, a multimeter and a capacimeter. You will investigate how capacitors behave in series and parallel and how voltages are distributed in capacitor circuits. With the given materials, complete the following tasks:
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
So large, in fact, that most capacitance measurements use microFarads ( F), nano (nF), and picoFarads (pF) as their unit of measure. The capacitance of a capacitor lled with a dielectric is given by C = C0, where C0 = Q= V0 is the capacitance in the absence of the dielectric, and is the dielectric constant.
Introduction Doing some simple experiments, including making and measuring your own capacitor, will help you better understand the phenomenon of capacitance.
As an example, a home cooling (AC) unit will have a capacitor that stores charge (energy). When the system is started, the capacitor can release the stored energy to assist the unit in starting the compressor necessary to cool the home. Electronics with flashing lights use a capacitor in a timing or RC circuit.

An Experiment to Determine Capacitance
An Experiment to Determine Capacitance . The reed switch is operated from a 400 Hz supply. It operates on the forward half cycle, to charge up the capacitor. No current flows on the reverse half cycle so the reed switch flies back to discharge the capacitor. We can use I = Q/t to work out the charge going onto the plates. We also know that f = 1/t, so we can combine the two …
