Question

Self-induction is the measure of coil’s ______.​

Answer 1

Answer:

emf=−LΔIΔt emf = − L Δ I Δ t , where L is the self-inductance of the inductor, and ΔI/Δt is the rate of change of current through it. The minus sign indicates that emf opposes the change in current, as required by Lenz's law. The unit of self- and mutual inductance is the henry (H), where 1 H = 1 Ω⋅s.

Answer 2

Answer:

Self-inductance or simply inductance is the process by which an emf is induced inside a coil of wire as a result of an alternating current traveling through that coil.

Explanation:

emf=−LΔIΔt emf = − L Δ I Δ t , where L is the self-inductance of the inductor, and ΔI/Δt is the rate of change of current through it. The minus sign indicates that emf opposes the change in current, as required by Lenz's law. The unit of self- and mutual inductance is the henry (H), where 1 H = 1 Ω⋅s.
