Hay bridge is NOT accurate, if the value of ‘Q’ of the inductor being measured is:

Correct option is D

​$$\begin{array}{|c|l|}\hline\textbf{Bridge} & \textbf{Application} \\\hline\text{Maxwell's Bridge} & \text{To measure inductance} \\\hline\text{Maxwell Wein Bridge} & \text{To measure a wide range of inductance at the power and audio frequencies but very expensive.} \\ & \text{Suitable for low Q coils (Q < 10)} \\\hline\text{Hay's bridge} & \text{To measure the high value of inductance. Suitable for high Q coils (Q > 10)} \\\hline\text{Anderson Bridge} & \text{Precise measurement of self-inductance over a wide range of values} \\\hline\end{array}$$​​
