Lab 3 Capacitors I get a real charge out of capacitors. P. W. Laws Objectives • To define capacitance and learn how to measure it with a digital multime- ter. • To determine how capacitance changes when capacitors are wired in par- allel and when they are wired in series. Overview Any two conductors separated by an insulator can be electrically charged so that one conductor has a positive charge and the other conductor has an equal amount of negative charge; such an arrangement is called a capacitor. A capacitor can be made up of two strange shaped blobs of metal or it can have any number of regular symmetric shapes such as that of one hollow sphere inside another, or one hollow rod inside another. The type of capacitor that is of the most practical interest is the parallel plate capacitor. Thus, we will focus exclusively on the study of the properties of par- allel plate capacitors. There are a couple of reasons why you will be studying parallel plate capacitors. First, the parallel plate capacitor is the easiest to use when making mathematical calculations or using physical reasoning. Second, it is relatively easy to construct. Third, parallel plate capacitors are used widely in electronic circuits to do such diverse things as defining the flashing rate of a neon tube, determining what radio station will be tuned in, and storing electrical energy to run an electronic flash unit.
