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...
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. ...
A useful, but slower, alternative is to put the inductor in parallel with a value of capacitance that will swamp stray capacitance values (500 pF or more) and find the resonance frequency, then calculate the inductance from this value. View chapter Book 2001, Passive Components for Circuit ...

A parallel conductance is placed across the + and – terminals of the primary and secondary windings, so that iL1 = i1 –G1v1, where G1 is the parallel conductance of the primary winding, and i1 is the terminal current into the primary. Similar definitions and equation apply to iL2. ...
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...
The reactance of an inductor is its resistance to alternating current. As the formula above suggests, the higher the frequency of the supply voltage, the higher the reactance of an inductor. This means that an inductor can act like a short circuit to low frequencies and an open circuit to ...
The mutual inductance calculator calculates the mutual inductance of 2 inductors with a coupling coefficient of k, according to the formula shown above. A user enters the coupling coefficient, K, inductor L1, and inductor L2, and the result will automatically be calculated and shown. The ...
Wheeler's general formula for a single layer coilis: , where dimensions are in cm. Finding the Equivalent "RQ" 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...
