Aim To verify the laws of combination of resistances (series and parallel) using a metre bridge. Apparatus and Material Required Principle When two resistances \(R_1\) and \(R_2\) are connected in series, the resistance of the combination \(R_S\) is given by \[R_S = R_1 + R_2\] When these two resistances are connected in parallel, the resistance of…
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 determine resistivity of two wires by plotting a graph for potential difference versus current. Apparatus and Material Required Principle According to Ohm’s Law, the current passing through a conductor is directly proportional to the voltage applied across it, as long as the conductor’s temperature and other physical properties remain constant. If I be the…
