Relation between frequency and inductance
WebNov 5, 2024 · Mutual inductance is the effect of two devices in inducing emfs in each other. A change in current ΔI 1 /Δt in one induces an emf emf2 in the seccond: EMF 2 = −M ΔI 1 … WebThe inductive reactance, XL, of a coil is an indication of the ability of a coil to produce self-induced voltage. Recall that inductive reactance is expressed mathematically as. The expression takes into consideration the rate of change of current in the circuit in terms of frequency (f) and the size of the inductor in terms of its value (L).
