Induction Motor How Does it Work (Basics Types

 · Synchronous speed is the speed of rotation of the magnetic field in a rotary machine and it depends upon the frequency and number poles of the machine. The induction motor always runs at speed less than its synchronous speed. The rotating magnetic field produced in the stator will create flux in the rotor hence causing the rotor to rotate. Due to the lag between the flux current in the rotor

How Does a Digital Scale Work Hunker

Basics. This digital scale measures the weight of a pen cap as 0.98 grams. Digital scales work with the use of a strain gauge load cell. Whereas analog scales use springs to indicate the weight of an object digital scales convert the force of a weight to an electric signal. Its key components consist of a strain gauge a device used to measure

CROCathode Ray Oscilloscope Working and Applications

Working Principle. The CRO working principle depends on the electron ray movement because of the electrostatic force. Once an electron ray hits a phosphor face then it makes a bright spot on it. A Cathode Ray Oscilloscope applies the electrostatic energy on the electron ray from two vertical ways.

Electronic Analytical Balance Wikiscales

For many years another apparent mass scale based on this principle had been in use. The basis of this scale was a brass weight whose density was specified to be 8.3909 g/cm3 at 20 °C with an air density of 0.0012 g/cm3. This scale is generally referred to as the "apparent mass vs. brass" scale. Balance Principles

Vernier Caliper Parts Types Working Principle Least

 · Here the main scale has the least count of 1mm and vernier scale has the least count of 0.9mm. So therefore 10 unit of the main scale is 1cm whereas 10 unit of vernier scale is 0.9mm. The unit of the vernier scale is 9mm. So this difference between the main scale and vernier scale which is 0.1mm is the working principle of vernier caliper.
