Project On Moving Coil — Galvanometer

A voltmeter must have and connect in parallel.

Theory: The voltage across G and S is equal. Since total current divides equally, G = S. project on moving coil galvanometer

Deflection per unit current. [ S_i = \frac\thetai = \fracnABk ] Unit: rad/A or div/A.

A galvanometer is a sensitive electromechanical instrument used to detect and measure small electric currents. Among various types, the is the most common and accurate. It operates on the principle that a current-carrying coil placed in a magnetic field experiences a torque. This project explores the suspended coil type (sensitive) and the pivoted coil type (robust). : A voltmeter must have and connect in parallel

Simultaneously, the suspension wire twists, producing a restoring torque (τ_rest) proportional to the angle of deflection (θ):

Since ( k, n, A, B ) are constants for a given instrument, . Hence, the scale is linear. Deflection per unit current
