Description : What is tachometer ? Explain photo electric pick-up
Answer : Tachometer is an instrument which is used to measure angular speed. It is measured in revolutions per minutes (RPM). Working: Working principle:The light passes through the holes available on the rotating disc with ... is given by N=f/HS N=speed f=frequency Hs=holes on the disc
Answer : It is a device used to measure the speed of a rotating shaft. It usually gives speed in RPM.
Description : A tachometer is a device used to measure (1) gravitational pull (2) speed of rotation (3) surface tension (4) dispersive power
Answer : speed of rotation
Description : State the use of Lux Meter and Tachometer in energy audit.
Answer : Use of lux meter – to measure intensity of light Use of tachometer – to measure speed
