A PROBLEM of some considerable importance to the practical engineer or physicist is that of calculating the effective self-induction of a circuit consisting of two parallel wires, the one being the return of the other. When the wires are not very close together, and their current is either ...
it exhibits a pure inductance. A common circuit of an inductor is shown below. It comprises of an ideal inductor with a parallel resistive component, that replies to AC. The direct current resistive component is in series with the inductor, and a capacitor is placed across the whole...
Since the "Q" of an inductor is the ratio of the reactive component to the resistive component, an equivalent circuit can be defined with a resistor in parallel with the inductor. This equation is valid only at a single frequency, "f," and must be calculated for each frequency of interest...
Inductance Conversion Formula The conversion between different inductance units is based on the following relationships: 1 H = 1,000 mH 1 mH = 1,000 µH 1 µH = 1,000 nH For example: Toconvert 5 mH to µH: 5 mH×1,000=5,000 µH. ...

Time for an excel formula or two.Inductors in parallel sum the same way as resistors: 1/(1/L1 + 1/L2 ...etc). Or (and I would):Approximate the inductance by working out the effective L for a single skinny wire of the length and thickness of your foil.Then parallel up the L's ...

The tables apply to calculations for equal circles with parallel axes, and to circles of nearly equal radii having inclined axes which intersect at the center of one of the circles. This latter case enters in the design of a variometer composed of two coils of small cross sections; the ...
