Usually, however, they are shown schematically. The schematic symbol for a voltmeter is a circle with the letter V, while the symbol for an ammeter is a circle with the letter I. The circuits of Figures 2–24 and 2–25 have been redrawn (Figure 2–26) to indicate this. (a) Voltmeter R E V (b) Ammeter I E R FIGURE 2–26 Schematic symbols for voltmeter and A voltmeter can be considered a pressure gauge, used to measure the electrical pressure in a circuit (Figure 6—6). Resistance is measured with an Ohmmeter. To measure resistance, a voltage is placed across the device to be measured, inducing a current flow through.the device (Figure 6—7). When there is little resistance, a large current flows and the FIGURE 6—7 (A) Schematic symbol for an ohmmeter.

NOTE: In electronics, analog devices are considered those in which voltage or current is represented as continuously varying. Digital devices are those whose Figure 12.10(B) illustrates the same circuit using symbols. Commonly used.electrical symbols can be found in Figure 12.11. Voltmeters are used to measure the potential difference between two points in an electric circuit and are therefore connected in parallel to the portion of the circuit between those points. The internal resistance of the voltmeter is very high so that the meter does not alter the current flow or the potential difference between the points being evaluated. Ammeters are Voltmeter Connection 245 Is voltage a through or an across parameter?

The receivingdepartment employees should be Battery Charging Panel Perhaps the first panel that the average electrician encounters is the storagebattery charging panel containing a voltmeter and an ammeter with the necessary field resistors. When these instruments are installed, they will be found to have Drawing. circuits. with. symbols. To make it easier to draw electrical circuits, scientists have devised a system of symbols for each.of the electrical components. Straight lines are used to represent connecting wires. A dot indicates where wires are joined. Light bulb • Ammeter • Voltmeter Two wires joined • Switch closed • Switch open Variable resistor Symbols used in circuit diagrams When you use these symbols, it is much easier to draw a circuit and identify its component parts.Connecting a voltmeter. Here is an example. Look at the lower connecting wire in Fig. 410. Sometimes, this may be replaced by the chassis as shown in Fig. 41 la. It makes no difference to the electrons. They flow through the chassis the same as they would through any conducting path. Ideally, we treat the chassis resistance as zero, so there is no voltage drop as the electrons flow.through the chassis. Figure 41 lb shows the schematic symbol used for the chassis. When you see this A wiring diagram, sometimes referred to as a schematic diagram, is a wonderful tool often compared to a road map. Suppose you were to find yourself in Salt Lake City for the first time and you were trying to get your new Ranger bassboat to Lake Mead to give her a spin. The first thing you would be likely to do is reach for a road map. Salt Lake City would be clearly shown on the map with graphic symbols that might tell you not only its location but its relative size, elevation, and in Watthour meter Wattmeter Synchroscope Voltmeter Contact making voltmeter Ammeter switch Voltmeter t A.Sw.
