Inductance, in electronics and electromagnetic concepts, is a property of current-carrying conductors whereby a change in current can result in generation of voltage (called electromotive force) in the conductor itself as well as a conductor placed in its vicinity. Inductance is linked with electromagnets and electromagnetism and it is described by Faraday's law of inductance.
The term inductance was first used by Oliver Heaviside in 1886, whereas the symbol for inductance (L) is in honor of Heinrich Lenz who devised many laws and principles of inductance. Inductance was first discovered by Faraday while studying charges in various experiments. However the name was later given to this phenomenon and Sir Joseph Henry independently discovered inductance, but after Faraday, and hence the SI unit to measure inductance is the Henry.
Two types of inductance exist, differing by the source of its production:
Both are ordinary inductances and differ only due to the circuit they are part of.
