Riegeleinteilung für eine SchützentafelTwo circuits are said to be . when the magnetic field produced by the current in one circuit induces an e.m.f. in the other circuit. The induced e.m.f., ., in the second circuit is.where . is the . (in henry, H) between the two circuits, and d./dt is the rate of change of the current in the first circuit.

Basic Concepts and D.C. Circuits,All units used by electrical and electronic engineers are part of the SI (Systéme International) system of units. Mechanical units are specified in terms of mass (the kilogramme [kg]), length (the metre [m]), and time (the second ). The basic units used are

Mesh Current and Node Voltage Analysis,Mesh current analysis can only be applied to a . i.e. a circuit which can be drawn on a plane surface. The circuit drawn in full line in Figure 2.1 is a planar circuit. However, if the branch shown in broken line between B and E is added, the circuit becomes nonplanar, and mesh current analysis cannot be used to analyse it.

Waveforms and Fourier Analysis,This chapter deals with . or repetitive waveforms in which .(.) = .(. + .) where . is an integer and . is the periodic time of the waveform (see Figure 3.1 for examples).

Reactance, Susceptance, Impedance and Admittance,When a resistanceless inductor is connected to a sinusoidal supply, the current which flows produces a magnetic flux. This, in turn, induces an e.m.f. in the inductor which opposes the flow of current, and restricts the current in the inductor. The r.m.s. magnitude of the current, ., in the inductor is
