Inductors and Magnetic Circuits Practice Quiz…

V = L * (di/dt) — The voltage across an inductor is directly proportional to the inductance (L) and the rate of change of current (di/dt).

X L = 2πfL — Inductive reactance is calculated by multiplying 2π, the frequency (f), and the inductance (L).

QF = X L / ESR — The quality factor is the ratio of inductive reactance (X L ) to the equivalent series resistance (ESR).

E = ½ * L * i 2 — The energy stored in an inductor is calculated as one-half times the inductance (L) times the square of the current (i).

L = (R 2 * n 2 ) / (9R + 10h) — The helical coil inductance is calculated using Wheeler's Formula.
