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 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 is the relation of Figure of merit with current sensitivity?
Figure of merit = 1/ Current Sensitivity.
What is the principle of ballistic galvanometer?
when current passes through a coil of b.g then it rotates in a magnetic field and measures the quantity of charge rather than current
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.
Figure of merit of galvanometer has dimensions?
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 is definition of figure of merit of galvanometer?
It is the amount if current it takes for unit deflection in the given galvanometer. k = I/theta Where k is the figure of merit, I is the current supplied and Theta equals the number of divisions of deflection.
What is figure of merit?
it is amount if current takes for unit diffection in given 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

What is the figure of merit of logic family?
A figure of merit correlated with the energyefficiency of a device. It can be calculated by the product of propagation delay time with power dissipation.
