Sample text
For instance, when a sound studio records a song, fluctuations in air pressure (that’s what sound is) move the diaphragm of a microphone, which produces corresponding variations in electrical current. That fluctuating current is a representation of the original sound, or an analog electrical signal. Digital systems, like computers, can’t handle continuous analog signals, so electrical signals must be converted into digital format before entering the depths of a digital system. Digital format is just another coding scheme which uses only the binary values 1 and 0 to represent information.
We discuss sources of electrical energy in Chapter 2. ✓ A load: The load is something that absorbs electrical energy in a circuit (for instance, a light bulb or a speaker). Think of the load as the destination for the electrical energy. ✓ A path: A conductive path provides a conduit for electrons to flow between the source and the load. An electric current starts with a “push” from the source and flows through the wire path to the load, where electrical energy makes something happen — emitting light, for instance.
So the electricity supplied by your average wall outlet is said to be 120 volts AC (or 120 VAC), which just means it’s alternating current at 120 volts. 25 26 Part I: Understanding the Fundamentals of Electronics Heaters, lamps, hair dryers, and electric razors are among the electrical devices that use 120 volts AC directly; clothes dryers, which require more power, use 240 volts AC directly from a special wall outlet. If your hair dryer uses 60 Hz power, and you’re visiting a country that uses 50 Hz power, you’ll need a power converter to get the hertz you need from your host country.
