How do you calculate the figure of merit of a galvanometer?

How do you calculate the figure of merit of a galvanometer?

We can find the figure of merit of the galvanometer by using the equation, k= E/(R+G)θ.

How is figure of merit calculated?

A figure of merit is a quantity used in representing the measure of effectiveness, efficiency, performance or any other important factor of a device, system, method and anything related to its alternatives. It is a numerical value that represents the performance of any device or system.

What is the figure of merit of moving coil galvanometer?

Galvanometer deflection is proportional to the amount of current passed through it. Figure of merit of a galvanometer is the reciprocal of current sensitivity. The resistance of the coil of the galvanometer is called the resistance of the galvanometer.

What is meant by figure of merit of a galvanometer write its formula and unit?

It is defined as the current which produces a deflection of one scale division in the galvanometer and is given by. G =θI=N.

How do you calculate deflection in galvanometer?

By closing the key K2 and adjusting the value of resistance in resistance box RBOX 2, you get the deflection θ/2 in the galvanometer. Then the resistance S equals G, the resistance of galvanometer, because half of the current passing through R is shared by S and half by galvanometer.

What is figure of merit of a galvanometer Class 12?

Figure of merit is in general is the numerical value representing the degree of effectiveness or efficiency of an instrument approximated by different estimation techniques.

What is the unit of figure of merit of a galvanometer?

The SI unit of the figure of merit of the galvanometer is Ampere per division. The figure of merit can be defined as the current required to produce unit deflection on the galvanometer.

What is figure of merit of galvanometer Class 12?

Figure of merit is in general is the numerical value representing the degree of effectiveness or efficiency of an instrument approximated by different estimation techniques. The figure of merit of a galvanometer is the current required to produce a deflection of one division in the galvanometer scale.

What is the figure of merit of the galvanometer if current I produce a deflection θ in it?

The figure of merit of the galvanometer 60μA/division. In the absence of shunt resistance, the galvanometer produces a deflection of θ=9 divisions when current flows in the circuit.

What is the figure of merit of the galvanometer if current I produce a deflection θ in it 2 points?

K = I/θ, where k is the figure of merit of the galvanometer.

How do you calculate the resistance of a galvanometer?

1. By closing the key K2 and adjusting the value of resistance in resistance box RBOX 2, you get the deflection θ/2 in the galvanometer. Then the resistance S equals G, the resistance of galvanometer, because half of the current passing through R is shared by S and half by galvanometer.
