What is the use of Tangent Galvanometer?
helps people fly to the moon if they are short on cash. better shut up if u don't know the answer !!
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.
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 galvanometer called sensitive instrument?
The galvanometer is called sensitive instrument because it can detect even very small magnitude of current and will show the deflection.
The device that turns a needle in a galvanometer is called an electromagnet?
True.
Reduction factor of tangent galvanometer?
it is the current measured in amphere..
What r the uses of tangent galvanometer?
to detect the sudden change in current.
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 are applications of ballistic galvanometer?
application of Ballistic Galvanometer 1) measurements of electric charges

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 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 galvanometer called sensitive instrument?
The galvanometer is called sensitive instrument because it can detect even very small magnitude of current and will show the deflection.
What is a segement that is tangent to a circle at an endpoint?
It is called a tangent segment.
