it is the current measured in amphere..
reduction factor is used to find earth's magnetic field and compare galvanometer constants
Reduction factor of the tangent galvanometer is actually numerically equal towards the current in ampere needed to produce a deflection of 45° in it whenever the plane of the coil lies together the magnetic meridian.
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)
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
to detect the sudden change in current.
IG=Betanx. in this G is G.constant, I is current, Be is Megnetic field of earth, OK? or anything else?
application of Ballistic Galvanometer 1) measurements of electric charges
helps people fly to the moon if they are short on cash. better shut up if u don't know the answer !!
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.
1) to calculate coeficient of error 2) to calculate deviation between the readings to infere a behaviour
A diliation is a reduction if the scale factor is: less than 1.
it mean that your gue hehehe
