At this point the polarity changes and the voltage increases from 0 to a negative 120 V, peaks, and again returns to 0 (Fig. 413). In the United States and Canada, public utilities deliver Current flow Power source AC –/+ +/– A Fig. 412 Simple electric circuit, alternating current (AC). The polarity of the power source alternates Simple alternator coil being rotated magnet slip rings spindle brushes current (generated to coil) Most modern generators are alternators The current they produce alternates in direction: it flows backwards, forwards, backwards, forwards and so on.as the generator turns. Current like this is called alternating current (AC). For example, the electricity which comes from the mains is AC. lt flows backwards and forwards 50 times every second. The current from a battery always flows in the Reactance is the opposition of a circuit element to a change of current, caused by the build–up of electric or magnetic fields in the element. Reactive element an inductor and capacitor. Reflected waves the waves reflected from a discontinuity in the medium they are traveling in. Resistance of an object is a measure of its opposition to the passage of a steady electric current. Resistor a lumped to differential signals. Skin effect is the tendency of an alternating electric current (AC) to A.battery, for example, supplies direct current. When charge flows back and forth sinusoidally, it is said to be alternating current, or AC. In the United States, the AC electricity delivered by the power company has a frequency of 60 cycles/s, or 60Hz. Examples of AC and DC are shown in Figure 2.3. FIGURE 2.3 (a) Steadystate direct current (DC) (b) Alternating current (AC). I I Time — MM Time —lHi lbl Using some basic physical properties of the conductor in which current flows, along Alternating current (ac) power sources produce a voltage that periodically reverses polarity and magnitude. An example of an ac power source is an ac generator. Alternating current has one major advantage over direct current; the voltage can be.increased or decreased by using a transformer. A transformer is an electrical device by which alternating current of one voltage is changed to another voltage. When electric current runs through a conductor, a magnetic field is produced.If someone asks you what your compression ratio is, you state your mechanical value instead of your corrected compression ratio. We sometimes describe torque in ftlb, when it's actually Ibft, and we call the CV carburetor a constant velocity carb, when it's correctly a constantvacuum carb. But in spite of all this, life still goes on. ALTERNATING CURRENT (AC) Alternating current, or AC, does what its name describes. With alternating current, the flow of electricity — or in our example, (e) Consuming.device (load) Example : Lamps, heater, fans, TV etc. 5.1 PATH OF ELECTRIC CURRENT To illuminate electric bulb as shown in Fig. 5.1 it is necessary to flow the current from the source of supply to an electric bulb. From the Fig. The wire or conductor through which the current starts from the source of supply to the bulb is called positive wire, main wire or live wire (in AC it is called wire). The wire or conductor through which the current returns back the source of supply Characteristics of currents from a standard TENS device Principles of electricity Electric current is the flow of electric charge through a medium. Electric charge can be For example, electric currents in liquid electrolytes, such as body fluids, are generated.by streams of positively and negatively charged ions. The rate of flow of Alternating current (AC) describes the flow of electric charge that periodically reverses direction, i.e. from positive to negative or vice versa. The relationship Table 81 outlines the differences between DC and AC. Electrical Measurements An electric current flows through a wire in the same way that water flows through a hose; however, without pressure, neither electricity nor water would flow. • The volt Tools and equipment that depend on electricity to function require different voltages; for example, clippers and blowdryers only require the 120 volts in normal wall sockets, while air conditioners and clothes dryers may require 240 volts.Type of.Current — a.c. indicates alternating current and d.c, direct current. Frequency — Shown in number of hertz (cycles per second). Even if voltages are similar, a 60hertz U.S. clock or tape recorder will not function properly on 50 hertz current. Number of phases — 1 and 3 are the conventional phases which may be available. Nominal voltages — Direct current nominal voltages, for example are: 110/220 and 120/240. The lower voltage is always 1/2 of the higher voltage.
