galvanometer as, Figure of merit of a galvanometer Figure of merit is in general is the numerical value representing the degree of effectiveness or efficiency of an instrument approximated by different estimation techniques. The figure of merit of a galvanometer is the current required to produce a deflection of one division in the galvanometer scale.EXPERIMENT AIM To determine the resistance of a galvanometer by halfdeflection method and to find its figure of merit. APPARATUS AND MATERIAL REQUIRED A moving coil galvanometer, a battery or a battery eliminator (0 6 V), figure of merit of galvanometer pdf

Galvanometer deflection is proportional to the amount of current passed through it. The resistance of the coil of the galvanometer is called the resistance of the galvanometer. Galvanometer has positive and negative terminals.

Feb 22, 2016 Figure of Merit of a Galvanometer: 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. It is the amount if current it takes for unit deflection in the given galvanometer. k Itheta Where k is the figure of merit, I is the current supplied and Theta equals the number of divisions of deflection. figure of merit of galvanometer pdf Figure of Merit of a Galvanometer.

Figure of merit of a galvanometer. Figure of merit is in general is the numerical value representing the degree of effectiveness or efficiency of an instrument approximated by different estimation techniques. The figure of merit of a galvanometer is the current required to produce a deflection of one division in the galvanometer scale. figure of merit of galvanometer pdf Jun 12, 2014 To determine the figure of merit of a galvanometer. To determine resistance of a galvanometer by halfdeflection method and to find its figure of merit. Apparatus A weston type galvanometer, a voltmeter, a battery or battery eliminator, two (10, 000 and 200 ) resistance boxes, two oneway keys, a rheostat, a screw gauge, a metre scale, an ammeter of given range, connecting wires and a piece of sand paper. Aim: To determine resistance of a galvanometer by half deflection method and to find its figure of merit. . Apparatus: A Weston type of galvanometer, a voltmeter, a battery battery eliminator, two 10, 000 ohm and 200 ohm ) resistance boxes, two one way key, a rheostat, a screw gauge, a meter scale, an ammeter of given range, connecting wires and a piece of sand paper. The resistance of the coil of the galvanometer is called the resistance of the galvanometer. Figure of merit of a galvanometer is the reciprocal of current sensitivity. Galvanometer deflection is proportional to the amount of current passed through it.
