What is a Strain Gauge?Strain Gauge DefinitionA strain gauge is a device that measures the deformation (strain) of an object when force is applied, through changes in electrical resistance.Working PrincipleThe strain gauge detects minute geometrical changes as resistance changes, which indicate the level of stress on the material.Bridge CircuitThe strain gauge is part of a bridge circuit, where it helps detect imbalances in resistance that correspond to stress, measured by a central voltmeter.Te
