1.1 Electri cation and Electric Charge
It is an experimental fact that a glass rod, after being briskly rubbed with a silk cloth, has the ability to attract bits of paper, straw, and other light objects to it. A glass rod in such a condition is said to be electri ed or charged, and to contain a kind of electric uid we ll call electric charge. Glass is not the only substance that can be electri ed by friction (rubbing), as almost all substances have this property to a greater or less degree. If a body is not electri ed it is said to be in an electrically neutral condition. Thus, a glass rod that has not been rubbed by a cloth is in an electrically neutral condition. Suppose we have a glass rod equipped with a rubber handle, as in Fig. 1. Let us suppose the glass rod has been charged by some means, as by rubbing with a silk cloth. We will nd that as long as we hold the assembly by the rubber handle the rod will stay electri ed, that is, will continue to hold its charge for a long period of time. This is because

CHAPTER 1 Electric Charge and Electric Field
the rubber handle is a good electrical INSULATOR, meaning that it does not allow the charge on the rod to leak o through it to the neutral earth. Thus, an electrical insulator is any substance that o ers great opposition to the movement or ow of electric charge through it. Rubber, porcelain, and dry wood are examples of good insulating materials. On the other hand, almost all metals o er very little opposition to the movement or ow of electric charge through them, and are said to be good CONDUCTORS of electric charge. Silver, copper, and aluminum, for example, are examples of very good conductors of electric charge. Of course, there is no such thing as a perfect insulator or conductor. A perfect insulator would allow no movement of charge through it, while a perfect conductor would o er no opposition to the ow of charge through it. For many practical purposes, however, substances like rubber, stone, quartz, and so on, can be considered to be perfect insulators, while substances like silver, copper, and gold can be considered to be perfect conductors of electric charge. Now suppose, in Fig. 1, that the glass rod is replaced by a charged copper rod. If we hold the assembly by means of the rubber handle only, the copper rod will of course continue to hold its charge. If, however, the charged rod is touched to a metal stake driven a foot or so into the earth (down to where the soil is moist), tests will then show that the copper rod has lost its electric charge. The explanation is that the charge carried by the rod was drained o into the earth through the metal stake, thus putting the rod back into its original uncharged, neutral condition. It should be pointed out that the earth is such a huge body that we are not able to change its state of charge to any noticeable degree; hence we will consider the earth to be, overall, an electrically neutral body at all times. Since we mentioned moist earth above, it should be mentioned that chemically pure water is a poor conductor. However, most ordinary tap water contains traces of metallic salts, and so on, so that such water is a fairly good conductor of charge. This brings up the point that, when making an electrical connection to the earth, we should go deep enough to get into moist soil; thus, a metal pipe driven only a short distance into dry soil would not be e ective in conducting electric charge to and from the earth. As mentioned before, all substances can be electri ed by friction (rubbing). We have already found that a glass rod becomes highly electri ed when rubbed briskly with a silk cloth. In the same way, we nd that a hard rubber rod becomes electri ed when rubbed with a piece of cat s fur. Such a rubber rod, when electri ed, will attract to it bits of paper and straw just as does an electri ed glass rod. Experiment, however, shows there is some kind of fundamental di erence between the charge that appears on the glass rod and the charge that appears on the rubber rod. To investigate further, let us denote glass and rubber rods as shown below.
We can now perform an experiment that will demonstrate that there are TWO KINDS of electric charge, one of which we will call positive and the other negative. The procedure is as follows. Let us charge two glass rods by rubbing with silk cloth, and two hard rubber rods by rubbing with cat s fur. Let us suppose the rods are then suspended from the ceiling by
