Noun
an electrical device (typically a conducting coil) that introduces inductance into a circuit
an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current
Source: WordNetA capacitor is placed across the points which absorbs the energy stored in the leakage inductance of the primary coil, and slows the rise time of the primary winding voltage to allow the points to open fully. Source: Internet
Additional energy is transferred from the primary to the secondary inductance and top-load capacitance during each "push", and secondary output voltage builds (called 'ring-up'). Source: Internet
Air core coils have lower inductance than ferromagnetic core coils, but are often used at high frequencies because they are free from energy losses called core losses that occur in ferromagnetic cores, which increase with frequency. Source: Internet
Air core inductors can use sliding contacts or multiple taps to increase or decrease the number of turns included in the circuit, to change the inductance. Source: Internet
Another method to control the inductance without any moving parts requires an additional DC current bias winding which controls the permeability of an easily saturable core material. Source: Internet
A normal (low leakage inductance) high-voltage transformer must use an external limiter (sometimes called a ballast) to limit current. Source: Internet
