In a Weston frequency meter, the magnetic axes of the two fixed coils are parallel perpendicular inclined at 60° inclined at 120° 2. If an inductance is connected in one arm of bridge and resistances in the remaining three arms the bridge can always be balanced the bridge cannot be balanced the bridge can be balanced if the resistances have some specific values 3. A power factor meter has one current circuit and two pressure circuits one current circuit and one pressure circuit two current circuits and one pressure circuit none of the above 4. The two pressure coils of a single phase power factor meter have the same dimensions and the same number of turns the same dimension but different number of turns the same number of turns but different dimensions none of the above 5. In a Weston synchronoscope, the fixed coils are connected across bus-bars incoming alternator a lamp none of the above 6. A Weston frequency meter is moving coil instrument moving iron instrument dynamometer instrument none of the above 7. In a vibrating reed frequency meter the natural frequencies of two adjacent reeds have a difference of 0.1 Hz 0.25 Hz 0.5 Hz 1.5 Hz 8. In a dynamometer 3-phase power factor meter, the planes of the two moving coils are at 0° 60° 90° 120° 9. In a single phase power factor meter the phase difference between the currents in the two pressure coils is exactly 0° approximately 0° exactly 90° none of the above 10. A Weston synchronoscope is a moving coil instrument moving iron instrument dynamometer instrument none of the above 11.
