A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
restoring torque is k theta the value of k depends upon the nature of the material used for suspension strip value of k is very small for quartz or phosphor bronze so in galvanometer phosphor bronze wire is used.
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.
take any magnetic material wrap a metal wire around it which conducts electricity and pass electricity through it
Yes. Copper is a very popular material used to make electrical wires.
a material that can be stretched into a wire
To build a galvanometer,you must have light coil ,a metallic ribbon and a permanent magnet. All you have to do is make the light coil of wire suspended from a metallic ribbon between the poles of a permanent magnet. And when current passes through the coil, the magnetic field it produces reacts with the magnetic field of the permanent magnet, producing a torque. Your galvanometer is ready .
Plastic cardboard, cloth and rubber are four substances that insulate wire.
Used as insulating material around wire cables since they do not conduct electricity. Used to make pan handles as they are poor conductors of heat. Used to make pan handles as they are poor conductors of heat.
