Answer to Question #282437 in Physics for chaitu

Question

1. Explain the construction and working of LVDT
2. Explain the construction and working of Strain gauge
3. Explain the working of a full-wave bridge rectifier with a neat circuit diagram and waveform.

Answer 1

1. LVDT (Linear Variable Differential Transformer) is a type of transformer with one primary and two secondary windings. The primary winding creates the magnetic flux, which induces AC currents in the secondary windings. The output voltage can be changed by moving the core within the transformer.
2. Strain gauge is a type of sensor that measures the external effort by measuring the electric potential difference across the terminals connected to a piezoelectric crystal.
