way of expressing the fact that the smaller the separation between the plates, the greater is the tendency for a given voltage v to cause breakdown of the dielectric material between the plates. Thus, when choosing capacitor dielectric material, the values of the dielectric constant K and the maximum permissible value of E must both be taken into account. A table of values for a few dielectric materials is given below, where small k stands for kilo (meaning thousand ). Thus, 2 kV 2 kilovolts 2000 volts, and kV=mm means kilovolts per millimeter (1 millimeter 0.001 meter).

Problem 111 If, in Fig. 121, the plate separation is 0.00065 meters and the dielectric material is dry air, what is the maximum voltage that should be applied to the capacitor In the discussion prior to Fig. 121, the term capacitance was introduced as being a measure of the ability of a capacitor to store electric charge. In this regard, let us suppose a current of i amperes is owing into, and out of, a certain capacitor in the direction shown in Fig. 122.

Since we have agreed to regard electric current as a ow of positive electric charge, it follows that, in Fig. 122, an excess of positive charge is accumulating on the left-hand plate, with a corresponding de ciency of positive charge on the right-hand plate. You will recall that electric charge is denoted by q and is measured in coulombs. The situation in Fig. 122 is that positive charge, accumulating on the left-hand plate, repels an equal amount of positive charge out of the right-hand plate, leaving the right-hand plate negatively charged. Thus if, at any instant of time, one plate of a capacitor has a charge of q coulombs, the other plate has an equal but opposite charge of q coulombs. We should of course note that, while the same current i ows into a capacitor as ows out, no current actually ows through the dielectric material between the plates.* What happens is that, as the current continues to ow, ENERGY is being stored in the electric eld between the plates, with a POTENTIAL DIFFERENCE building up between the two plates. In Fig. 122, for example, as the current continues to ow in the direction shown, a potential di erence of v volts, having the polarity as shown, builds up across the capacitor. With the foregoing in mind, let us return to the term capacitance which, as previously stated, is to be a measure of the ability of a capacitor to store electric charge.

In this regard, it s apparent that, for any given capacitor, the amount of stored charge depends rst upon the amount of voltage, v, and second upon items (1), (2), and (3), listed following Fig. 121, that is, upon the physical construction of the capacitor in question. All these factors are taken into account by de ning that the CAPACITANCE of a capacitor is equal to the ratio of the magnitude of the stored charge to the potential di erence between the plates; thus, by de nition, q 184 C v where q magnitude of charge, in coulombs, stored on either plate, v potential di erence, in volts, between the plates, C capacitance of the capacitor, in FARADS (for Michael Faraday). Capacitance is thus measured in coulombs per volt, which is called farads. The farad is a very large unit of capacitance; in almost all practical work we deal with microfarads (millionths of a farad) and picofarads (millionths of a microfarad). Letting F denote farads, mF * (or sometimes mfd ) microfarads, and pF picofarads, the conversion factors are F 106 mF F 1012 pF mF 106 pF and thus ; F mF 10 6 F pF 10 12 mF pF 10 6

Problem 112 If a dc voltage of 290 volts is applied to a capacitor having 0.015 mF of capacitance, what magnitude of charge is stored on either plate We have noted that ENERGY is stored in the electric eld between the plates of a capacitor. A formula, giving the amount of such energy, can be found as follows. To begin, let us recall that, basically, the potential di erence in volts between the two plates is equal to the work, W, in joules, required to move one coulomb of charge against the eld from the negative plate to the positive plate. Thus volts is basically equal to joules divided by coulombs, v W=q. Now suppose we have a capacitor with zero volts potential di erence between the two plates, and then suppose we begin to move very small amounts of positive charge from one plate to the other plate. Suppose we continue to do this until we have transferred a total of q coulombs of charge, thus producing a potential di erence of v volts between the plates. Doing the above is equivalent to moving an average amount of charge of q=2 coulombs through a potential di erence of v volts, and thus the total work done is (from above, work volts coulombs) W v q=2 vq=2 joules which, since there are no losses due to friction, is now all stored as POTENTIAL ENERGY in the electric eld between the plates of the capacitor. Or, by eq. (184), writing Cv in place of q, the above equation becomes W 1 Cv2 2 185
where C capacitance of the capacitor, in farads, v potential di erence in volts between the two plates, and W energy, in joules, stored in the electric eld.
