What are the construction of galvanometer?
galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.
Steps in making a galvanometer?
Wind a coil of wire around a bobbin to create the coil, which will serve as the moving element of the galvanometer. Attach a pointer or index needle to the coil to indicate the deflection caused by the current passing through the coil. Place the coil and pointer assembly within a magnetic field produced by a permanent magnet to allow for the deflection of the pointer in response to current flow. Connect the coil to a calibrated scale to measure the amount of current based on the deflection of the pointer.
What is weston galvanometer?
A weston galvanometer is a type of sensitive instrument used to detect and measure small electric currents. It uses a moving coil suspended in a magnetic field to deflect in response to the current passing through it. This deflection is then used to indicate the strength of the current.
What are the main parts of a galvanometer listed?
The main parts of a galvanometer are the coil, a magnet, a spring, a pointer, and a scale. The coil is connected in series with the circuit and produces the magnetic field. The magnet provides a magnetic field that interacts with the coil's field, causing deflection of the pointer. The spring provides the restoring force to bring the pointer back to its original position, and the scale is used to measure the deflection.
What The distance that the pointer of a galvanometer moves depends on the amount of magnetism in the loops of the armature?
The distance that the pointer of a galvanometer moves is determined by the strength of the magnetic field present in the coils or loops of the armature. When an electric current flows through the coils, it interacts with the magnetic field produced by the coils, resulting in a deflection of the pointer. The greater the magnetism in the loops, the larger the deflection of the pointer.

What cause the pointer to move in a galvanometer?
Basically, the pointer moves due to measuring the direct current (flow of electric charge) through an electric circuit.
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.
What energy transformation occurs in galvanometer?
It transforms into a magnetic field.
How much can the wire loop in a galvanometer turn?
The wire loop in a galvanometer can typically turn up to 90 degrees due to the magnetic field generated by the current flowing through it. This movement is restricted to allow for accurate measurement of the current passing through the galvanometer.
What is used to turn the pointer of a galvenometer?
The pointer on a galvenometer moves due to magnetic force between the current carrying coil in the pointer assembly and the permanent magnet surrounding that coil.
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
What is critical dumping of ballistic galvanometer?
Critical damping of a ballistic galvanometer refers to the minimum amount of damping required for the galvanometer's pointer to return to zero without oscillating after being deflected. This ensures a rapid but smooth response to changes in current, preventing overshooting or settling time delays in measurements. Achieving critical damping involves balancing the resistive and inductive components of the galvanometer's damping system.
