Connect the electrometer to the capacitor. Connect the black wire from the electrometer to the fixed plate of the capacitor and the red wire to the movable plate. Zero the electrometer (refer to the instructions in lab 1 if you don’t remember how) and select the 30 volt range on the function switch. 3.
The capacitance of the electrometer and cable is approximately 20 pF (1 pF = 1 pico Farad = 10-12 Farad). The experimental result should be close to this value. (4 pts) Why is it sufficient to add charges to only one plate?
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
The capacitance C1 of the electrometer and cable is in parallel with the test capacitor of capacitance C2. Therefore, C1 can be calculated according to The capacitance of the electrometer and cable is approximately 20 pF (1 pF = 1 pico Farad = 10-12 Farad). The experimental result should be close to this value.
The capacitance of the electrometer and cable C1 adds to the external capacitor which is connected in parallel. Therefore, it is necessary to know the capacitance of the electrometer and cable in order to have an accurate measurement of the capacitance of an external capacitor. Connect the circuit as shown in Fig. 2.
