1. (n.)inductance the property of a circuit by which a change in current induces, by electromagnetic induction, an electromotive force.
Etymology: (1885–90)
Definition of 'Inductance'

1. (noun)induction, inductance an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current
1. Inductance The property of a circuit in virtue of which it exercises induction and develops lines of force. It is defined variously. As clear and satisfactory a definition as any is the following, due to Sumpner and Fleming: Inductance is the ratio between the totalinduction through a circuit to the current producing it. "Thus taking a simplehelix of five turns carrying a current of two units, and assuming that 1,000 lines of force passed through the central turn, of which owing to leakage only 900 thread the next adjacent on each side, and again only 800 through the end turns, there would be 800 + 900 + 1000 + 900 + 800, or 4,400 linkages of lines with the wire, and this being with 2 units of current, there would be 2,200 linkages with unit current, and consequently the self-inductance of the helix would be 2,200 centimetres." (Kennelly.) Inductance, as regards its dimensions is usually reduced to a length, hence the lastword of the preceding quotation.
[Transcriber's note: (L (di/dt) = V). A current changing at the rate of one ampere per second through a one henryinductance produces one volt. A sinusoidal current produces a voltage 90 degrees ahead of the current, a cosine (the derivative of sine is cosine). One volt across one henry causes the current to increase at one ampere per second.]
