Which of the following statements are correct about AC Bridges? (A) The Maxwell bridge is suitable for the measurement of Medium Q Coils (1 < Q < 10). (B) For measurements at low frequencies, the power line may serve as a source of excitation, while at higher frequencies, an oscillator supplies excitation voltage. (C) The Hay bridge is convenient for measuring very low Q coils (Q < 1). (D) The Schering bridge is particularly useful for measuring insulating properties, i.e., for phase angles nearly 90°.
