Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
Scale used in moving coil meter is?
Linear Scale
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
What does positive of the coil mean?
The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
What is the function of an electrical coil in a basic circuit?
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.
Moving coil galvanometer converted into a multi range ammeter?
yes
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What are the disadvantages of a moving coil galvanometer?
major disadvantage is that moving coil galvanometer is not suitable for a.c measurement
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
What are the kinds of ammeter?
The ammeter is a device that measures the electric current. Hot wire, electrostatic, moving iron, moving coil, and induction are the kinds of ammeter.
What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
What does mc and mi refer to in voltmeter and ammeter?
moving coil & moving iron
What is coil galvanometer meter and its application?
Moving coil galvanometre is a device which is used to detect current in a curcuit.
Working of moving-coil galvanometer?
A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.
How do you convert a galvanometer to an ammeter?
A galvanometer is an instrument used to measure and detect electric currents. While that seems a lot similar to an ammeter, it only deals with measuring relatively small or mediocre currents. Although an ammeter is now much preferred due to its more accurate, faster, and advanced readings, there is a way to "convert" a galvanometer to function like an ammeter. A current separator or divider, known as a shunt, allows a simple meter to be calibrated (adjusted) to measure larger currents. The shunt, parallel to the coil of your galvanometer, allows more electric currents to circulate around the circuit, thus obtaining more current.
Why is it necessary to have some form of controlling couple in the moving coil galvanometer?
To stop the moving coil from movement as if there wasnt any opposite couple the coil will complete rotating and this wouldnt help measurement.
What are the important questions in intermediate first year physics?
moving coil galvanometer
