Electrical cell itch? Switch Resistor Ammeter I Voltmeter Figure 1.19 Simple electric circuit The following terminology is used for electrical circuits. • Open circuit — the switch is OFF and no current flows. • Closed circuit — the switch is ON and current flows. Electrical circuits use circuit symbols which are a type of shorthand. Table 1 .6 shows examples of the symbols used in electrical circuit diagrams.

TYPES. OF. METERS. An ammeter is used to measure current in a circuit. An ammeter (schematic symbol shown in Figure 6–4) can be considered a flow meter. It measures the number of electrons flowing past a given point in a circuit. The electrons must flow through the ammeter to obtain a reading. As shown in Figure 6–5, this is accomplished by opening the circuit and inserting the ammeter. FIGURE 6–4 Schematic symbol for an ammeter.

WHEN electrical instruments are received, they are almost invariably TYPICAL SYMBOLS FOR METER WIRING otherwise mislaid and consequently may never reach those persons to whom.the work of connecting the instruments is assigned. The receivingdepartment employees should be instructed that the instruction cards or PLEASE NOTE that these polarities refer to conventional current flow, so the current should enter the meter at the red terminal and leave via the black terminal. The ammeter circuit symbol is shown in Fig. 1.14. A Fig. 1.14 As you would expect, a voltmeter is used for measuring voltages; in particular, p.d.s. Since a p.d. is a voltage between two points in a circuit, then this meter is NOT connected into the circuit in the same way as an ammeter. In this sense it is a simpler instrument to use, If a separate ammeter and voltmeter were placed in this circuit the voltmeter would give a steady reading.of the nominal 400V and the ammeter would read the nominal 50A, the product of which would be 20,000VA. A wattmeter in the same circuit would, as explained, multiply the instantaneous values of voltage and current and the product in this case would be 12,000W. Figure 4.9 shows the components of the power triangle, which are Component Symbol Formula Unit Active power Practical Application A schematic diagram of a simple circuit is shown in figure 60. The positive terminal of the 12 volt battery is connected by a wire conductor (called a lead) to the positive terminal of an ammeter. A second Find the current when the battery voltage (as indicated on the voltmeter) is 12 volts and the resistance is 3 ohms; proceed as follows: (1).Express the known values in terms of the symbols representing them: £"=12 volts R=3 ohms /=?
