Convortion of moving coil galvanometrr into voltmeter?

A galvanometer can be converted into a voltmeter by connecting it with very high resistance.


Which voltmeter will used for measuring 50kv dc?

Any standard voltmeter but however the voltage to be measured must be stepped down to a safe value using a Potential transformer.


Is Voltmeter is a moving iron Instrument or moving coil instrument?

If this is a homework related question, you really should consider trying to solve it yourself before looking at this answer. Otherwise, the value of the lesson, and the reinforcement provided by the assignment, will be lost to you.A moving coil measuring instrument has a coil attached to the indicator, surrounded by a magnet.A moving iron measuring instrument has a magnet attached to the indicator, surrounded by a coil.In both cases, the indicator is driven by magnetic torque caused by current flow in the coil.


Can instrument transformers be used to extend the range of a moving coil voltmeter?

Not directly, as MC instruments are direct-current instruments, whereas instrument transformers only work on a.c.


Why a DC voltmeter and DC ammeter cannot read AC?

Obviously, it's a voltmeter that measures a.c. voltages. The most common types are a 'moving iron' type or a 'moving coil' type. The latter requires a rectifier circuit. Both scales are calibrated to indicate root-mean-square values. Moving-iron scales are non-linear, whereas moving-coil scales are linear. Moving-iron types are less accurate than moving-coil types.

How can you say that ac emf is induced in the coil?

When we place a current carrying conductor in a magnetic field emf is induced in a coil. we can knoe it by connecting voltmeter.


Why you called the watt-meter as dynamo-meter in the 3 phase power measurement?

The terms you are looking for are 'dynamometer' (no hyphen!) or 'electrodynamic' instrument. These terms describe an instrument movement, where the torque applied to the pointer results from the interaction of magnetic fields produced by fixed and moving coils. In the case of a wattmeter, the fixed coil is the current coil which is connected in series with the load, and the moving coil is the voltage coil which is connected in parallel with the load.A dynamometer type instrument differs from a moving-coil instrument, such as an ammeter or a voltmeter, in which the torque applied to the pointer is the result of the interaction between the magnetic fields produced by the moving coil and a permanent magnet.For three-phase power measurements, it is possible to use just two wattmeters in a configuration called the 'two wattmeter method'.


What are the types of galvanometer?

The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.

Is megger related to hot wire instrument moving coil or moving iron?

Megger is related to a hot wire instrument with a moving coil. The megger uses a moving coil to measure insulation resistance in electrical circuits and equipment. This type of instrument is specifically designed for insulation testing.
