Moving Coil Ballistic Galvanometer assignment help, Moving Coil Ballistic Construction. Work done in twisting the suspension wire by an angle θ = 1/2cθ 2. A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. In operation the unknown quantity of charge Q (in coulombs) is simply: Q = k d {\displaystyle Q=kd} Q=kd. Its construction is similar to that of a ballistic galvanometer, but its coil is suspended without any restoring forces in the . A ballistic galvanometer is one used to measure an electrical blow, or impulse. In the field of projectile, this instrument is useful in motion.

What is Galvanometer? – Definition, Construction & Working Principle – Circuit Globe

Thanks for your comment. Educalingo cookies are used to personalize ads and get web traffic statistics. The upper end of the suspension fibre is connected to a rotating screw head so that the plane of the coil can be adjusted in any desired position. The following are the methods used for determining the constant of the ballistic galvanometer.

We are working to help as many students as we can. When an electric charge is connected to the instrument, the coil starts moving in the magnetic field of the galvanometer’s magnet, generating an opposing electromotive force and coming to a stop regardless of the time of the current flow.


We also share information about the use of the site with our social media, advertising and analytics partners. Examples of use in the English literature, quotes and news about ballistic galvanometer. The iron core provides the low reluctance flux path and hence provides the strong magnetic field for the coil to move in.

The moving coil, suspension, and permanent magnet are the main parts of the galvanometer. It is suspended by means of a phosphor bronze wire between the poles of a powerful horse-shoe magnet.

Thank u very much.

Moving Coil Galvanometer (M.C.G.)

When the charge passes through the galvanometer, their coil starts moving and gets an impulse. The definition of ballistic galvanometer in the dictionary is a type of galvanometer for workijg surges of current. The suspended type consists of a rectangular coil of thin insulated copper wires having a large number of turns.

The email has already been used, in case you have forgotten the password click here. Its construction is similar to that of a ballistic galvanometer, but its coil is suspended without any restoring forces in the suspension thread or in the current leads.

Eliyaraja October 9, Circuit Globe All about Electrical and Electronics. The q be the total charge passes through the coil. The calibration of the galvanometer is the process of determining its constant value by the help of the practical experiments. I would like to receive suggestions and corrections from your side.


In ballistic galvanometercopper wire coil is bound on a non-conducting frame, the moment of inertia of the coil is large and its suspension has a small torsional constant. As the galvanometer and the shunt resistance are connected in potential with galvsnometer circuit, their potentials are equal. A cylindrical soft iron core C is place symmetrically inside the coil between the magnetic poles which are also made cylindrical in shape.

Balllistic upper end of the suspension wire and the lower end of the spring are connected to terminals T1 and T2. Priyanka June 1, 5: Meaning of “ballistic galvanometer” in the English dictionary.

It consists of a rectangular coil of thin copper wire baplistic on a non-metallic frame of ivory. Md khalid raza September 19, The expression gives the angular momentum of the coil. Circuit Globe All about Electrical and Electronics. It can be either of the moving coil or moving magnet type. It is really an integrator measuring the quantity of charge discharged through it. The mechanical strength of the wire is not very strong, and hence the galvanometers handle carefully without any jerks.

Thus, accurate reading is obtained.
