Aim– Measurement of Inductance by Anderson’s Bridge. Material Required– Anderson Bridge Trainer Kit, Wires Theory– The Anderson bridge is a bridge circuit used for measuring unknown resistances, especially those with high values. The bridge is balanced when the ratio of the resistances in the adjacent arms is equal. Circuit Diagram- Formula used and derivation – […]

Aim- Measurement of Resistance by Wheatstone Bridge. Apparatus- Galvanometer (0-10V), Decade Resistance Box, Resistance (4), Bread Board, Power Supply Theory- The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistance is equal, and no current flows through the circuit. When the bridge is balanced, the galvanometer reads zero. This

BASIC INSTRUMENTAION AND MEASUREMENT TECHNIQUESStrain Gauge Aim: Study of strain measurement using strain gauge and cantilever assembly. Apparatus Required: Theory: The strain gauge module consists of a cantilever beam which is fixed on a rigid body. The strain gauge which are fixed above the beam detects the longitudinal strain and fixed below the beam detects transversal strain. When
