The method of loop currents, introduced in section 4.4, applies to ac networks as well as dc networks. All we need do is properly label the ac network, then apply the rules laid down in that section. To illustrate the procedure, let us now work through the solution of an ac network problem using the loop current method. In doing this, we ll go into much more detail than a person normally would in working such a problem; we do this, of course, to emphasize the fundamental ideas involved. Thus, for purposes of basic explanation, let us begin with our example network expressed in terms of the fundamental variable time, t, as shown in Fig. 104, in which resistance values are in ohms. The voltages and currents are sinusoidal, as always, with the voltage and current arrows having the meanings described in the discussion following eq. (108). In the gure, note that only the (peak) generator voltages, including their polarity arrows and their phase angles, and the resistance values are given. The unknowns are thus the peak values, Ip1 and Ip2 , of the current waves and their corresponding phase angles a and b, and the peak value Vp of the output voltage wave vo and its phase angle c.{ All phase angles are to be stated with reference to the voltage wave, 43 sin !t, which, since it passes through the origin of the horizontal time axis, will be said to have zero phase Reading Code128 In Visual Studio .NET Using Barcode reader for Visual Studio .NET Control to read, scan read, scan image in VS .NET applications.

(Since the angular amount !t is in radians, the phase angles a, b, c, as they appear in the gure, must also be expressed in radians.) In the gure, let the voltage appearing across the 12ohm resistor be the output voltage of the network. Thus vo is the instantaneous value of the output voltage. As time continues to increase, vo continually swings back and forth, sinusoidally, between the positive and negative peak values Vp and Vp . Now let the basic PROBLEM be to FIND THE MAGNITUDE OF THE RMS VOLTAGE that would appear across the 12ohm load resistor (this being the value of voltage that would be read by an ac voltmeter connected across the 12ohm resistance). To solve the above problem by the method of loop currents, let us begin by returning to the threestep procedure outlined in section 4.4. The threestep rule, as given in Chap. 4, was applied to dc circuits; it should be emphasized, however, that the rules apply AT ANY AND ALL INSTANTS OF TIME in any network. This is true because Kirchho s current and voltage laws (sections 4.2 and 4.3) are, and must be, satis ed at any and all instants of time in any network. Now, in regard to our problem here and the abovementioned three steps, notice that we automatically satis ed step I when we drew and labeled the current arrows in Fig. 104. Next, step II de nes the rules to be used in writing the VOLTAGE EQUATIONS around each of the n loops in a network (n 2 in Fig. 104). The same rules, given in the original statement of step II in section 4.4, will also apply to the ac circuit of Fig. 104 except that now the plus and minus battery polarity marks will be replaced by voltage arrows associated with each ac generator (see Fig. 89). Thus the original statement of step II would now, for the alternatingcurrent (ac) case, be stated as follows. All generator voltages will be written on the righthand sides of the equations, and will be considered positive if we go through a generator with the voltage arrow, but negative if we go through the generator against the voltage arrow. The original statement about voltage drops across resistors will remain unchanged. Thus, applying these step II rules to the ac network of Fig. 104, we have the following two voltage equations, which are valid at all instants of time, rst around the lefthand loop (eq. (122)), then around the righthand loop (eq. (123)). 18Ip1 sin !t a 8Ip2 sin !t b 43 sin !t 36 sin !t 5=6 8Ip1 sin !t a 20Ip2 sin !t b 36 sin !t 5=6 64 sin !t =3 122 123 Making DataMatrix In .NET Using Barcode generator for VS .NET Control to generate, create ECC200 image in .NET framework applications.
