Applications of reduction factor of tangent galvanometer?
reduction factor is used to find earth's magnetic field and compare galvanometer constants
What is galvanometer constant of tangent galvanometer?
IG=Betanx. in this G is G.constant, I is current, Be is Megnetic field of earth, OK? or anything else?
What is a common tangent?
A common tangent is a line which is tangent to two (or more) curves.
What is the differential equation of the circle tangent to y axis?
dy/dx = (r - x)/sqrt(2xr - x2) , I hope!
Which construction uses the compass for only one step in addition to drawing the circle itself?
The construction that uses the compass for only one additional step, aside from drawing the circle, is the construction of a tangent to a circle from a point outside the circle. In this process, the compass is first used to draw the circle, and then it is used again to find the point where the tangent line touches the circle, typically by constructing a radius to that point and creating a right triangle to determine the tangent's direction.
Why tangent galvanometer is called tangent galvanometer?
A tangent galvanometer is called so because it uses the tangent of the angle through which a magnetic needle is deflected to measure electric current. The horizontal component of the Earth’s magnetic field and a coil carrying current creates a magnetic field that deflects the needle, making it tangent to the circle of the coil.

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.
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)
Why you should take four times reading in tangent galvanometer?
1) to calculate coeficient of error 2) to calculate deviation between the readings to infere a behaviour
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 does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
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.
