Why is the lamp and scale arrangement in a ballisitics galvanometer at a distance of 1 meter from the galvanometer?
for the convenience of calculations
What is ballistic galvanometer.Give the construction and theory of moving coil ballistic galvanometer.?
a ballistic galvanometer is a specially designed galvanometer suitable for measuring the total quantity of electricity or charge displaced by a varying current of short duration such as charging & discharging of a capacitor >>>>
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.
What is a stable galvanometer?
When current is passed throgh a galvanometer, the coil oscillates about its mean position before it comes to rest. To bring the coil to rest immediately, the coil is wound on a metallic frame. Now, when the coil oscillate, eddy currents are set up in the metallic frame, which opposes further oscillations of the coil. This inturn enables the coil to attain its equilibrium position almost instantly. Since the oscillation of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.
How do you produce electricity from magnetism?
One way you can produce electricity is by using a U shaped magnet and pushing a metal string in the U shaped magnet!You use a galvanometer attached to the string and when you push it, it will become electrical energy! (A galvanometer measures electricity.)
Applications of reduction factor of tangent galvanometer?
reduction factor is used to find earth's magnetic field and compare galvanometer constants
Reduction factor of tangent galvanometer?
it is the current measured in amphere..
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 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
What r the uses of tangent galvanometer?
to detect the sudden change in current.
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
A dilation is a reduction if the scale factor is?
A diliation is a reduction if the scale factor is: less than 1.

it mean that your gue hehehe
