At current loops, the loss in the line conductors is exaggerated. At voltage loops, the loss in the line dielectric is increased. At minima, the losses are decreased. But overall, in a mismatched line, the losses are greater than they are in a perfectly matched line.

Generating QR Code In C#.NET Using Barcode printer for VS .NET Control to generate, create Quick Response Code image in VS .NET applications. 318 Power and resonance in ac circuits This loss occurs at heat dissipation. It is true power. Any true power that goes into heating up a transmission line is wasted, because it cannot be dissipated in the load. The additional loss caused by standing waves, over and above the perfectlymatched line loss, is called standingwave loss. The greater the mismatch, the more severe the standingwave loss becomes. The more loss a line has to begin with (that is, when it is perfectly matched), the more loss is caused by a given amount of mismatch. Standingwave loss increases with frequency. It tends to be worst in long lengths of line at VHF, UHF, and microwaves.

Data Matrix ECC200 Creation In None Using Barcode printer for Software Control to generate, create DataMatrix image in Software applications. A severe mismatch between the load and the transmission line can cause another problem: physical destruction of the line! A feed line might be able to handle a kilowatt (1 kW) of power when it is perfectly matched. But if a severe mismatch exists and you try to feed 1 kW into the line, the extra current at the current loops can heat the conductors to the point where the dielectric material melts and the line shorts out. It is also possible for the voltage at the voltage loops to cause arcing between the line conductors. This perforates and/or burns the dielectric, ruining the line. When a line must be used with a mismatch, derating functions are required to determine how much power the line can safely handle. Manufacturers of prefabricated lines can supply you with this information. EAN13 Printer In None Using Barcode printer for Software Control to generate, create EAN13 image in Software applications.

GTIN  128 Maker In None Using Barcode creator for Software Control to generate, create UCC128 image in Software applications. One of the most important phenomena in ac circuits, especially in radiofrequency engineering, is the property of resonance. You ve already learned that resonance is a condition that occurs when capacitive and inductive reactance cancel each other out. Resonant circuits and devices have a great many different applications in electricity and electronics. Recall that capacitive reactance, XC, and inductive reactance, XL, can sometimes be equal in magnitude. They are always opposite in effect. In any circuit containing an inductance and capacitance, there will be a frequency at which XL XC. This is resonance. Sometimes XL XC at just one frequency; in some special devices it can occur at many frequencies. Generally, if a circuit contains one coil and one capacitor, there will be one resonant frequency. Refer to the schematic diagram of Fig. 1711. You might recognize this as a series RLC circuit. At some particular frequency, XL XC. This is inevitable, if L and C are finite and nonzero. This is the resonant frequency of the circuit. It is abbreviated fo.

Recognize Bar Code In VB.NET Using Barcode scanner for VS .NET Control to read, scan read, scan image in .NET applications. At fo, the effects of capacitive reactance and inductive reactance cancel out. The result is that the circuit appears as a pure resistance, with a value very close to R.

Calculating resonant frequency 319 R 0, that is, the resistor is a short circuit, then the circuit is called a series LC circuit, and the impedance at resonance will be extremely low. The circuit will offer practically no opposition to the flow of alternating current at the frequency fo. This condition is series resonance. ECC200 Printer In None Using Barcode maker for Font Control to generate, create DataMatrix image in Font applications. Generating Barcode In Visual C#.NET Using Barcode drawer for VS .NET Control to generate, create bar code image in Visual Studio .NET applications. Parallel resonance
Refer to the circuit diagram of Fig. 1712. This is a parallel RLC circuit. You remember that, in this case, the resistance R is thought of as a conductance G, with G 1/R. Then the circuit can be called a GLC circuit. 1712 A parallel RLC circuit.
At some particular frequency fo, the inductive susceptance BL will exactly cancel the capacitive susceptance BC; that is, BL BC. This is inevitable for some frequency fo, as long as the circuit contains finite, nonzero inductance and finite, nonzero capacitance. At the frequency fo, the susceptances cancel each other out, leaving zero susceptance. The admittance through the circuit is then very nearly equal to the conductance, G, of the resistor. If the circuit contains no resistor, but only a coil and capacitor, it is called a parallel LC circuit, and the admittance at resonance will be extremely low. The circuit will offer great opposition to alternating current at fo. Engineers think more often in terms of impedance than in terms of admittance; low admittance translates into high impedance. This condition is parallel resonance.
