Question

Which range and unit description apply to the coefficient of coupling \[K\] ?

Options

• \[0\leq K\leq 1\]; measured in volts

• \[0\leq K\leq 1\]; dimensionless, no units

• \[K<0\]; measured in Weber

• \[K>1\]; measured in Henry

Answer 1

The coefficient of coupling is a fraction, so its range is \[0\leq K\leq 1\] . It is dimensionless and has no units.
