Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
The experiment can be repeated with different capacitors. Plot a graph of Q against V. Episode 126-2: Measuring the charge on a capacitor (Word, 47 KB) The second investigation of the relationship between charge and pd makes use of a change-over reed switch. Students may have met simple on/off reed switches in technology or even in primary school.
A simple capacitor is the parallel plate capacitor, represented in Figure 1. The plates have an area A and are separated by a distance d with a dielectric ( ) in between. The plates carry charges +Q and Q, respectively, on their surfaces. The capacitance of the parallel plate capacitor is given by
Procedure and Computations The true value of each of the capacitors involved in the calibration may be defined as the nominal value plus a correction; thus, the true capacitance of the uncalibrated 100-pf capacitor is S= Sn+s, where Sn= lOO (exactly) and s is the small correction.
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.
Determine the relationships between charge, voltage, and stored energy for a capacitor. Relate the design of the capacitor system to its ability to store energy. Position the top foil strip one inch over the piece of paper (Note: do not let the pieces of foil touch each other!).

When the capacitors are connected in series Charge and current is same on all the capacitors. For series capacitors same quantity of electrons will flow through each capacitor because the charge on each plate is coming from the adjacent plate. So, coulomb charge is same. As current is nothing but flow of electrons, current is also same.

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 …
