What is the use of Tangent Galvanometer?

A Tangent Galvanometer is used to measure small electric currents in a circuit. It works on the principle of the tangent law of magnetism, where the magnetic needle aligns with the magnetic field produced by the current passing through a coil. This alignment allows for the measurement of the current based on the angle of deflection of the needle.


How tangent galvanometer is used to determine the horizontal component of earth's magnetic field?

by using the formula b=μn/2A(I/TAN Ɵ)....where μ=4πx10 pow(-7)n=number f turns of the coilA=radius of the coil(m)I=current flowing through the coil(A)Ɵ=angle of deflection in the tangent galvanometer.


What is a galvanometer called when calibrated to read current?

A galvanometer calibrated to read current is called an ammeter. It is used to measure the flow of electric current in a circuit.


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.


Why needle of tangent galvanometer move by increasing and decreasing current?

The galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component He of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electrical current flow through the galvanometer coil, a second magnetic field H is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. These two perpendicular magnetic fields add vertically, and the compass needle points along the direction of their resultant He + H. The current in the coil causes the compass needle to rotate by an angle\ \theta.

What is reduction factor of tangent galvanometer?

The reduction factor of a tangent galvanometer is the ratio of the tangent of the angle of deflection produced by a given current to the actual value of that current. It is used to calibrate the instrument so that the deflection angle can be directly related to the current flowing through it.


How do you find reduction factor of tangent galvanometer?

We find it by varying the current flowing through it and by measuring the deflection respectively and then we use the formula k=I/tan(theta)
