Aim To find resistance of a given standard resistor using metre bridge. Apparatus and Material Required Description of the Apparatus Meter BridgeMeter bridge consists of one-meter-long constantan wire with uniform cross-sectional area and three thick metal strips, two bent at ninety-degree angles. Mounted on a wooden board marked with a scale, these components create a setup…

Aim To study the variation in potential drop with length of a wire for a steady current. Apparatus and Material Required Principle If a steady current is flowing through a wire with uniform cross section and constant resistance per unit length, potential drop \(V\) across two points of the wire is directly proportional to the length…
