What is Ballistic galvanometer Explain its construction?
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
What are the construction of galvanometer?
galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.
What is figure of merit of a ballistic galvanometer?
It is defined as the current which produces a deflection of one scale division in the galvanometer and is given by, G= k/NBA where, k is the torsion constant. N is the number of turns in the coil B is the magnetic field and, A is the ares of cross section of the coil.
Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
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 is ballistic galvanometer.Give the construction and theory of moving coil ballistic galvanometer.?
a ballistic galvanometer is a specially designed galvanometer suitable for measuring the total quantity of electricity or charge displaced by a varying current of short duration such as charging & discharging of a capacitor >>>>
What are applications of ballistic galvanometer?
application of Ballistic Galvanometer 1) measurements of electric charges
Why damping is small in ballistic galvanometer?
to get critical damped system

Principle of multimeter?
Based on the principle of the D'Arsonval galvanometer, the main function of a multimeter is measuring a circuit's voltage, current, and resistance.
Two things which work on the principle of biotech and chemtech?
Two things which work on the principle of biotech and chem tech is a galvanometer apparatus and fire extinguisher.
What is a description of the principle of a meter bridge?
it work on the principal of balanced wheat stone bridge ..i.e the reading of galvanometer shows 0 ..
What is figure of merit of a ballistic galvanometer?
It is defined as the current which produces a deflection of one scale division in the galvanometer and is given by, G= k/NBA where, k is the torsion constant. N is the number of turns in the coil B is the magnetic field and, A is the ares of cross section of the coil.
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
