It's denoted by 'M'. The formula of the inductance L = μ N 2 A l, here L is the inductance, μ permeability, N number of turns in coil, A area encircled by coil, l and length of the coil. One is the mutual inductance and another one is self-inductance. Sep 25, 2024 · Learn more about Mutual Inductance in detail with notes, formulas, properties, uses of Mutual Inductance prepared by subject matter experts. Dimensional formula of R2C/LResistance (R), capacitance (C), and inductance (L) are all physical quantities with their own units and dimensions.
