A clamp-type measuring instrument operates on the principle of?
INDUCTION
What is the working principle of geophone?
Geophone Are Moving Coil Electromagnetic type principle is contained
What type of input device uses the principle of magnetic induction to produce a voltage signal?
Hard Drives Floppy Drives Tape Drives Drum Drives
Why induction type instrument canot be used for dc measurements?
Induction is a property of voltage changes, which does not occur with Direct Current devices. There are exceptions, such as the coil of an automobile, which charges up to a high voltage between ignition discharges, but the voltage supplying the coil does not vary.
What type of induction motor used in ceilinf fan?
Could be a single phase induction motor of 20-40 watts.
A clamp-type measuring instrument operates on the principle of?

What is induction type instrument give example and explain in detail?
Induction-type instrument measure power in alternating-current circuits and are the type commonly seen on the outside of houses.
WORKING principle of permanent magnet moving coil instrument?
The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale. The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)

What is the Difference between dynamo meter type watt meter and simple watt meter?
S. No.Dynamometer Type WattmetersInduction Type Wattmeters1.The instrument can be used on both dc and ac systems.The instrument cannot be used on dc system.2.The instrument can have high degree of accuracy.If carefully designed.The instrument is less accurate. It is accurate only at stated frequency and temperature3.Power consumption is comparatively low.Power consumption is comparatively higher4.Weight of moving system is comparatively low.Weight of moving system is comparatively higher5.The instrument has uniform scale.The instrument has uniform and long scale6.The instrument has comparatively weaker working torque.The instrument has comparatively stronger working torque.
Could an induction type instrument be used to measure a pulsing DC signal of varying voltage?
Yes. As the DC is pulsed or varied in voltage, it will induce a varying magnetic field which can be detected with another inductor.
Explain the Working principles of dynamometer type wattmeter?
Induction type wattmeters operate on the same principle on which induction type ammeters and voltmeters operate. Advantages. The advantages of induction wattmeters are the same as those of induction ammeters-long scale, freedom from effects of stray field, and good damping. Disadvantages. (i) Change in temperature causes variations in the resistance of the moving element, affects the eddy currents therein, and so the operating torque. The error due to this is in part offset by a balancing effect due to change in temperature of the windings. (ii) Change in frequency from that of the calibration value causes variations in both the reactance of the voltage coil circuit, which is highly inductive, and also in the amount of compensation from the phase-compensating circuit. Within the limits of frequency variation met within practice on the mains, this last error is not important.
What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
