Why tangent galvanometer is set into magnetic meridian?
A tangent galvanometer is set into the magnetic meridian to ensure that its plane is aligned with the Earth's magnetic field. This alignment allows for accurate measurement of the magnetic field produced by an electric current flowing through the coil of the galvanometer. When the galvanometer's coil is positioned in this way, the angle of deflection of the needle directly corresponds to the tangent of the ratio of the magnetic field due to the current to the Earth's magnetic field, facilitating precise calculations.
Why is it called as reduction factor in tangent galvanometer?
The term "reduction factor" in a tangent galvanometer refers to the ratio of the magnetic field strength produced by the coil of the galvanometer to the Earth's magnetic field strength. It quantifies how much the deflection of the galvanometer's needle is reduced due to the presence of the magnetic field generated by the coil compared to the Earth's magnetic field. This factor is essential for accurately measuring current in the circuit by relating the tangent of the angle of deflection to the current flowing through the coil.
What is the use of spirit level in the tangent galvanometer?
A spirit level in a tangent galvanometer is used to ensure that the device is perfectly horizontal. This alignment is crucial for accurate measurements of the magnetic field and current, as any tilt can introduce errors in the readings. By leveling the galvanometer, the magnetic needle can respond correctly to the magnetic field produced by the current flowing through the coil. A proper setup ensures reliable and consistent results during experiments.
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.
Reduction factor of tangent galvanometer?
it is the current measured in amphere..
What is galvanometer constant and how to find it?
The galvanometer constant is the factor that relates the deflection of a galvanometer to the current passing through it. It is usually given as the current required to produce a unit deflection (such as one full-scale deflection) on the galvanometer. To find the galvanometer constant, you can pass a known current through the galvanometer and measure the corresponding deflection, then calculate the constant as the current divided by the deflection.

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?
