Transient Voltage and Current Amplitudes in Inductively Coupled Circuits

When two circuits are so placed that energy may be transferred from one to the other they are said to be coupled. If the coupling is obtained by a circuit element (resistor, capacitor or coil) common to both circuits the coupling is direct. If the circuits are linked only by a magnetic field the coupling is called inductive. This paper will concern itself only with inductively coupled circuits. The steady state characteristics of this network are, a high gain and good frequency selectivity. Thus it finds extensive use in communication work. There are many texts which give excellent analyses of the steady state characteristics of this circuit. Morecrofts\u27 text Principles of Radio Communication” is particularly good
