Characteristic admittance is the mathematical inverse of the characteristic impedance The general expression for the characteristic admittance of a transmission line is A transmission line is drawn as two black wires At a distance x into the line there is current phasor I x traveling through each wire and there is a voltage difference phasor V x between the wires bottom voltage minus top voltage If Y0 displaystyle Y 0 is the characteristic admittance of the line then I x V x Y0 displaystyle I x V x Y 0 for a wave moving rightward or I x V x Y0 displaystyle I x V x Y 0 for a wave moving leftward Y0 G jwCR jwL displaystyle Y 0 sqrt frac G j omega C R j omega L where R displaystyle R is the resistance per unit length L displaystyle L is the inductance per unit length G displaystyle G is the conductance of the dielectric per unit length C displaystyle C is the capacitance per unit length j displaystyle j is the imaginary unit and w displaystyle omega is the angular frequency The current and voltage phasors on the line are related by the characteristic admittance as I V Y0 I V displaystyle frac I V Y 0 frac I V where the superscripts displaystyle and displaystyle represent forward and backward traveling waves respectively See also editCharacteristic impedanceReferences editGuile A E 1977 Electrical Power Systems ISBN 0 08 021729 X Pozar D M February 2004 Microwave Engineering 3rd ed ISBN 0 471 44878 8 Ulaby F T 2004 Fundamentals Of Applied Electromagnetics media ed Prentice Hall ISBN 0 13 185089 X Retrieved from https en wikipedia org w index php title Characteristic admittance amp oldid 1007962446, wikipedia, wiki, book, books, library,
