Voltage Division You ve learned how voltage dividers can be designed using resistors. The resistors dissipate some power in doing this job, but the resulting voltages can provide the proper biasing of electronic circuits. This ensures, for example, that an amplifier or oscillator will function in the most efficient, reliable way possible. Bias The term bias means, in the case of a bipolar transistor, a field-effect transistor, or a vacuum tube, that the control electrode the base, gate, or grid is provided with a certain voltage, or made to carry a certain current, relative to the emitter, source, or cathode. Networks of resistors can accomplish this. A radio transmitting amplifier is biased differently than an oscillator or a low-level receiving amplifier. Sometimes voltage division is required for biasing. Other times it isn t necessary. Figure 6-1 shows a bipolar transistor whose base is biased using a pair of resistors in a voltage divider configuration. Current Limiting Resistors interfere with the flow of electrons in a circuit. Sometimes this is essential to prevent damage to a component or circuit. A good example is a receiving amplifier. A resistor can keep the

Different elements can join together to share electrons. When this happens, the result is a chemical compound. One of the most common compounds is water, the result of two hydrogen atoms joining with an atom of oxygen. There are literally thousands of different chemical compounds that occur in nature.

transistor from using up a lot of power just getting hot. Without resistors to limit or control the current, the transistor can be overstressed carrying direct current that doesn t contribute to the signal. Figure 6-2 shows a current-limiting resistor between the emitter of a bipolar transistor and electrical ground.

10 Basic physical concepts A compound is different than a simple mixture of elements. If hydrogen and oxygen are mixed, the result is a colorless, odorless gas, just like either element is a gas separately. A spark, however, will cause the molecules to join together; this will liberate energy in the form of light and heat. Under the right conditions, there will be a violent explosion, because the two elements join eagerly. Water is chemically illustrated in Fig. 1-3.

Power Dissipation The dissipation of power in the form of heat is not always a bad thing. Sometimes a resistor can be used as a dummy component, so a circuit sees the resistor as if it were something more complicated. When testing a radio transmitter, for example, a resistor can be used to take the place of an antenna. This keeps the transmitter from interfering with communications on the airwaves. The transmitter output heats the resistor without radiating any signal. But as far as the transmitter knows, it s connected to a real antenna (Fig. 6-3) and a perfect one, too, if the resistor has just the right ohmic value!

Compounds often, but not always, appear greatly different from any of the elements that make them up. At room temperature and pressure, both hydrogen and oxygen are gases. But water under the same conditions is a liquid. If it gets a few tens of degrees colder, water turns solid at standard pressure. If it gets hot enough, water becomes a gas, odorless and colorless, just like hydrogen or oxygen. Another common example of a compound is rust. This forms when iron joins with oxygen. While iron is a dull gray solid and oxygen is a gas, rust is a maroon-red or brownish powder, completely unlike either of the elements from which it is formed.

The real evolution, of course, came with the birth of the personal computer. Thanks to Bill Gates and his concept of a simple operating system such as DOS and Steve Jobs with his vision of computing for the masses, truly ubiquitous computing became a reality. From the perspective of the individual user, this evolution was unparalleled. The

Another situation in which power dissipation is useful is at the input of a power amplifier, such as the sort used in high-fidelity audio equipment. Sometimes the circuit driving the amplifier (supplying its input signal) has too much power. A resistor, or network of resistors, can dissipate this excess so that the amplifier doesn t get too much drive. In any type of amplifier, overdrive (an excessively strong input signal) can cause distortion, inefficiency, and other problems.
