Download Solution PDFConcept:
The coefficient of coupling (k) between two coils indicates how effectively energy is transferred from one coil to another through mutual inductance. It is a dimensionless quantity ranging from 0 (no coupling) to 1 (perfect coupling).
Calculation
The formula for coefficient of coupling is:
\( k = \frac{M}{\sqrt{L_1 \cdot L_2}} \)
This formula expresses how mutual inductance relates to the geometric mean of the self-inductances of the two coils.
Hence, the correct option is the one showing: M / √(L₁L₂)
