How can you make a galvanometer sensitive
Web72.03 -- EMF induced by moving magnet. A wire coil is connected to a galvanometer. When you push a magnet towards the center of the coil, then pull it away, the galvanometer needle deflects in one direction, then the other. How far the needle deflects depends on the strength of the magnet and how fast you move it. WebThe sensitivity of a Moving Coil Galvanometer is the ratio of the change in deflection of the galvanometer to the change in current. Therefore we write, Sensitivity = dθ/di. If a galvanometer gives a larger deflection for a small current it is a sensitive galvanometer. The current in Moving Coil galvanometer is: I = (C/nBA) × θ

Web11 de jan. de 2024 · A ballistic galvanometer consists of a copper wire coil of large moment inertia, wounded and non-conductive frame. If this coil is wounded on conductive frame then there will be induced current due to which there will be electromagnetic damping. So by using non-conductive frame there will be no induced emf and have no electromagnetic … WebBy connecting a high resistance in series connection with a galvanometer, it can be converted into a voltmeter. The resistance is connected in series with the galvanometer …

WebA tangent galvanometer can also be used to measure the magnitude of the horizontal component of the geomagnetic field. When used in this way, ... The string galvanometer is a type of mirror galvanometer so sensitive that it was used to make the first electrocardiogram of the electrical activity of the human heart. Ballistic galvanometer Web5 de abr. de 2024 · We know that for the conversion of a galvanometer into a voltmeter, a high resistance is required. So, if the resistance of the galvanometer is G and that of the high resistance is R, when they are connected in series, the total resistance of the arrangement becomes the following: RSeries = G + R. Now, the galvanometer behaves …
