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?
Applications of reduction factor of tangent galvanometer?
reduction factor is used to find earth's magnetic field and compare galvanometer constants
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!
What is the tangent of 39?
Tangent 39 = 0.809784033195
Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
Reduction factor of tangent galvanometer?
it is the current measured in amphere..
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
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.
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)
What is reduction factor of tangent galvanometer?
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.
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.
How galvanometer measure the exact voltage with series high resistor?
Assuming galvanometer has zero or negligible internal resistance. If u connect resistor R>>RL(Load resistance) and connect it parallel to RL, it will hardly cause any change in voltage across load resistance. Suppose small current Ig goes through galvanometer. Since galvanometer have zero internal resistance, Voltage across RL = Voltage across R = IgR
