EAN13 Creator In None Using Barcode encoder for Software Control to generate, create EAN13 image in Software applications. Problem 132 What will be the inductive reactance of the preceding coil if the supply is a battery that supplies pure dc Because dc has a frequency of zero, XL = 6.28 0 0.500 = 0 . That is, there will be no inductive reactance. Inductance doesn t have any practical effect with pure dc. Problem 133 If a coil has an inductive reactance of 100 at a frequency of 5.00 MHz, what is its inductance In this case, you need to plug numbers into the formula and solve for the unknown L. Start out with the equation 100 = 6.28 5.00 L = 31.4 L. Because the frequency is given in megahertz, the inductance will come out in microhenrys. You can divide both sides of the equation by 31.4, getting L = 100/31.4 = 3.18 H.

Inductive reactance can be plotted along a half line, just as can resistance. In a circuit containing both resistance and inductance, the characteristics become twodimensional. You can orient the resistance and reactance half lines perpendicular to each other to make a quarterplane coordinate system, as shown in Fig. 135. Resistance is plotted horizontally, and inductive reactance is plotted vertically upward.

In this scheme, resistanceinductance (RL) combinations form complex impedances. (The term impedance comes from the root impede, and fully describes how electrical components impede, or inhibit, the flow of ac. You ll learn all about this in Chap. 15.) Each point on the RL plane corresponds to one unique complex impedance value. Conversely, each complex impedance value corresponds to one unique point on the RL plane. You might ask, What s the little j doing in Fig. 135 For reasons that will be made clear in Chap. 15, impedances on the RL plane are written in the form R + jXL, where R is the resistance in ohms, and XL is the inductive reactance in ohms. The little j is called a j operator and is a mathematical way of expressing the fact that reactance is denoted at right angles to resistance in compleximpedance graphs. If you have a pure resistance, say R = 5 , then the complex impedance is 5 + j 0, and is at the point (5,0) on the RL plane. If you have a pure inductive reactance, such as XL = 3 , then the complex impedance is 0 + j3, and is at the point (0,j3) on the RL plane. These points, and a couple of others, are shown in Fig. 136. In real life, all coils have some resistance, because no wire is a perfect conductor. All resistors have at least a tiny bit of inductive reactance, because they take up some physical space and they have wire leads. So there is really no such thing as a mathematically perfect pure resistance such as 5 + j 0, or a mathematically perfect pure reactance like 0 + j3. But sometimes you can get extremely close to theoretical ideals in real life. Often, resistance and inductive reactance are both deliberately placed in a circuit. Then you get impedances values such as 2 + j3 or 4 + j1.5. These are shown in Fig. 136 as points on the RL plane. Remember that values for XL are reactances, not actual inductances. Because of this, they vary with the frequency in an RL circuit. Changing the frequency has the effect of making complex impedance points move around in the RL plane. They move vertically, going upward as the ac frequency increases, and downward as the ac frequency decreases. If the ac frequency goes down to zero, the inductive reactance vanishes. Then XL = 0, we have pure dc, and the point is right on the resistance axis.
