Strain Gauge | Working, Types, Diagram, Applications
A strain gauge is an example of a passive transducer that converts a mechanical displacement into a change of resistance. It is a thin, waferlike device that can be attached to a variety of materials by a suitable adhesive to measure the applied strain. As the structure is stressed, the resulting strain deforms the strain gauge attached to the ...

What is a DC Machine : Construction Its Working ElProCus
A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor. DC Machine

The amplifier basically changes the dc voltage provided by the supply into ac power. This ac signal is then given to the tank circuit through a feedback path. Further, the oscillations of the tank circuit are fed to the amplifier. Since the amplifier amplifies the applied input at its terminal. Thus, at the output of the amplifier, amplified ...
