R bar (high temperature line)

Inductance is an attribute of closed circuit and a physical quantity. When the current passes through the coil, a magnetic field induction is formed in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. It is a circuit parameter that describes the induced electromotive force effect in this coil or in another coil due to the change of coil current. Inductance is the general term of self-induction and mutual inductance. The device that provides inductance is called inductor.
