Want this question answered?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
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.
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
A sensitive galvanometer cannot be stable. Explain Why?
IG=Betanx. in this G is G.constant, I is current, Be is Megnetic field of earth, OK? or anything else?
reduction factor is used to find earth's magnetic field and compare galvanometer constants
We can find it by using wheatstone bridge.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
The current is reversed in a galvanometer
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
No, you have to use the reflux integer i=53^-32 which is a constant. This formula will help;
