IN THIS CHAPTER, YOU LL LEARN MORE ABOUT DC CIRCUITS AND HOW THEY behave. These principles apply to almost all circuits in utility ac applications, too. Sometimes it s necessary to analyze networks that don t have obvious practical use. But even a passive network of resistors can serve to set up the conditions for operation of a complex electrical device such as a radio amplifier or a digital calculator, by providing specific voltages or currents.
Current through series resistances
Have you ever used those tiny holiday lights that come in strings If one bulb burns out, the whole set of bulbs goes dark; then you have to find out which bulb is bad, and replace it to get the lights working again. Each bulb works with something like 10 V; there are about a dozen bulbs in the string. You plug in the whole bunch and the 120-V utility mains drive just the right amount of current through each bulb. In a series circuit, such as a string of light bulbs (Fig. 5-1), the current at any given point is the same as the current at any other point. The ammeter, A, is shown in the line between two of the bulbs. If it were moved anywhere else along the current path, it would indicate the same current. This is true in any series dc circuit, no matter what the components actually are and regardless of whether or not they all have the same resistance. If the bulbs in Fig. 5-1 were of different resistances, some of them would consume more power than others. In case one of the bulbs in Fig. 5-1 burns out, and its socket is then shorted out instead of filled with a replacement bulb, the current through the whole chain will increase, because the overall resistance of the string would go down. This would force each of the remaining bulbs to carry too much current. Another bulb would probably burn out before long. If it, too, were replaced with a short circuit, the current 82

would be increased still further. A third bulb would probably blow out almost right away after the string was plugged in.
Voltages across series resistances
The bulbs in the string of Fig. 5-1, being all the same, each get the same amount of voltage from the source. If there are a dozen bulbs in a 120-V circuit, each bulb will have a potential difference of 10 V across it. This will be true no matter how large or small the bulbs are, as long as they re all identical. If you think about this for a moment, it s easy to see why it s true. Look at the schematic diagram of Fig. 5-2. Each resistor carries the same current. Each resistor Rn has a potential difference En across it, equal to the product of the current and the resistance of that particular resistor. These En s are in series, like cells in a battery, so they add together. What if the En s across all the resistors added up to something more or less than the supply voltage, E Then there would have to be a phantom EMF some place, adding or taking away voltage. But there is no such. An EMF cannot come out of nowhere. This principle will be formalized later in this chapter. Look at this another way. The voltmeter V in Fig. 5-2 shows the voltage E of the battery, because the meter is hooked up across the battery. The meter V also shows the sum of the En s across the set of resistors, because it s connected across the set of resistors. The meter says the same thing whether you think of it as measuring the battery voltage E, or as measuring the sum of the En s across the series combination of resistors. Therefore, E is equal to the sum of the En s. This is a fundamental rule in series dc circuits. It also holds for 60-Hz utility ac circuits almost all the time.
