WebX = RL2/L1 = R (100 – L)/L. And the specific resistance of the material for a given wire is obtained by the relation = (3.14) r2X/l. where, r = the radius of the cable and also l = length of the wire. The devices required in finding … WebMar 8, 2024 · The above figure shows a meter bridge. A Meter bridge is an electrical instrument based on the Wheatstone bridge which is useful for determining the unknown resistance of any material. In this instrument, a one-meter wire is used with unknown resistance. The cross-sectional area of the wire is uniform. This wire is connected to a …

WebShown here is a voltage and current meter panel from a three-phase AC system. The three “donut” current transformers (CT’s) can be seen in the rear of the panel. Three AC ammeters (rated 5 amps full-scale deflection each) on the front of the panel indicate current through each conductor going through a CT. WebIn the meter bridge circuit shown, the null point is obtained at C(AC=x) on the wire AB. If the diameter of the wire AB is doubled, the position of the new null point C' will correspond to. Q. Write the principle on which the working of a metre bridge is based. WebMar 31, 2024 · Now the jockey is moved along the wire AC till there is no deflection in the galvanometer. This is the balanced condition of the Wheatstone bridge. ... Meter bridge is in balanced state shown in figure. Resistance of per unit length of the meter bridge wire is 1 Ω/cm. asked Mar 31, 2024 in Electric Circuit by Abhinay (62.9k points) oxford immunology lab handbook
