Self-Inductance of a Single Core Cable

The self­inductance of a single core cable is a property that describes the electromotive force caused by the change in current in the cable.

The self\[Hyphen]inductance of a single core cable increases with the length and the logarithm of the ratio of the sheath and conductor radii increase.

Formula

QuantityVariable["L", "MagneticInductance"] == Log[QuantityVariable[Subscript["R", "1"], "Radius"]/QuantityVariable[Subscript["R", "2"], "Radius"]]*Quantity[1/(2*Pi), "MagneticConstant"]*QuantityVariable["l", "Length"]

symbol description physical quantity
L self­inductance "MagneticInductance"
R1 sheath radius "Radius"
R2 conductor radius "Radius"
l length "Length"
