Aside from the term ground, or earth ground, there are two other terms related to ground that we must define: Neutral, or circuit common, and chassis ground. The schematic symbols for each type are illustrated in Figure 3—2. Neutral, or Circuit Common The circuit Neutral, also referred to as a circuit common, is a common point in an electrical circuit from which voltage measurements are taken. A voltage measurement is a 2point differential measurement. When voltages are measured Ready for some electronics schematic doubletalk? When it comes to labeling ground connections in schematics, it's common practice to use the symbol for earth ground (which is a real connection to the earth) to represent the common ground (the reference

point.for 0 volts) in a circuit. (Chapter 2 details these two types of grounds.) More often than not, the “ground” points in lowvoltage circuits are not actually connected to earth ground; instead, they're just tied to each other — hence The transformer being used to isolate the triac works at line voltage, from the lowvoltage control circuit. Figure 28.10(a) shows the symbol for a triac. A diac is a twoterminal trigger device fabricated as a gateless triac that triggers by breakdown at a designed low voltage and is often used in the gate circuit of a thyristor or triac. Figure 28.10(b) shows the schematic symbol for the diac. At low voltages or either polarity, a diac is completely nonconducting; however, once its

These thermostats are often preferred over the linevoltage version because • They reduce the risk of severe electric shock because of the low amperage draw. • They tend to be less expensive than linevoltage thermostats. • In most geographical areas, the associated wiring can be installed RC RCM The last four symbols indicate different ways of labeling switches. The first indicates that the switch is a part of a lowvoltage wiring system. An RCM indicates that it is a master switch on a lowvoltage control that will override

the.action of individual switches or perform the same action that several of the single switches would perform. The lowercase letter identifies that this is switch "a." This letter will appear at all the luminaires (fixtures) that this switch controls. The final symbol A ladder diagram is a standard method for developing and documenting the electrical interconnections necessary to build a control system. The finished diagram can Ladder diagrams have two basic sections, the line voltage section at the top of the ladder, and the lowvoltage section at the bottom of the ladder. A transformer separates of the ladder diagram. More complex ladder diagrams are developed by placing schematic symbols for additional components into

(Source: Delmar/Cengage Saturating the transistor causes the collectoremitter voltage to drop to between 0.04 and 0.03 volt. This small voltage drop allows the IGBTs can be driven into saturation to provide a very low voltage drop between the emitter and collector, but they do not suffer from the slow recovery time of common junction transistors.

The difference is the direction of the Decreasing the amount of negative voltage (again, notice the size of the battery) applied to the gate will cause the current flow from source to drain to increase, as shown in Figure 21–56. JFETs have a higher internal JFET will typically measure 0 volt. If you measured a low value in both instances, the sourcegate junction is probably shorted.
