Question 6A18
Element 6 (Radiotelegraph)The property of a conductor or coil which causes a voltage to be developed across its terminals when thenumber of magnetic lines of force in the circuit or coil is changed is:
Explanation
Inductance is the property of a conductor or coil that causes a voltage to be developed across its terminals when the magnetic field (lines of force) through it changes. This phenomenon is described by Faraday's Law of Induction, which states that a changing magnetic flux through a coil induces an electromotive force (EMF) or voltage. The coil "inducts" this voltage in response to the changing magnetic field, opposing the change that caused it (Lenz's Law).
Capacitance is the ability to store an electrical charge in an electric field, typically between two conductive plates separated by a dielectric, and is unrelated to voltage induced by a changing magnetic field. Conductance is the measure of how easily current flows through a material, the reciprocal of resistance, and also does not describe this inductive effect.
