Resistance Of Galvanometer By Half Deflection Method Pdf Download
A galvanometer is a device used to detect feeble electric currents in a circuit. It consists of a coil suspended between the poles of a powerful magnet. As current passes through the coil, it deflects. It can be detected from the deflection on galvanometer needle. The deflection is proportional to the current passed through it.
To verify the laws of combination (parallel) of resistances using a metre bridge. To determine resistance of a galvanometer by half-deflection method and to find its figure of merit.
