Vibration meter  : Vibration Meters : measure vibration in velocity, acceleration, RMS, peak-to-peak and displacement. A vibration meter can be used to monitor and diagnose problems in bearings, machines, engines and more. Prevent costly and expensive mechanical failures by using a tool that can understand your machinery overall to help you identify  problems   faster     Vibration testing can provide early warnings of machine failure, giving maintenance staff time to repair.               Q 01  : What is vibration monitoring system?  Ans:   Vibration monitoring systems are used for condition-based maintenance of machines and installations. They help to detect machine damage in good time and prevent costly consequential damage. ... Vibration transmitters and sensors detect damaged bearings and unbalance in drives and rotating machine parts. ...

  ( Solenoid voltage  tester )        Also   known in the trade by the nickname   " wiggies," are also multi-function testers, but they are somewhat simpler and easier to use than the battery-operated multimeters. Both analog and digital models are available. Solenoid volt meters are capable of testing for both voltage and polarity. Electricians use them frequently because they can test both AC voltage and DC voltage in a range from 100 to 600 volts. Pros often prefer this tool over the multimeter for many applications, since it is very rugged and has no batteries to monitor. It is not, however, quite as accurate as a multimeter for providing a numerical measurement of how much voltage is present.  Solenoid testers have two wires, each with a probe, extending out of the bottom of the tester. Solenoid testers do not use batteries to power them, so they are always ready to check voltage. The announce the presence of voltage by clicking or vibr...

(Q)      👇                                     What is mutual inductance explain?   (Ans) Mutual Inductance Is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil. In the previous tutorial we saw that an inductor generates an induced emf within itself as a result of the changing magnetic field around its own turns. 😎

 Q (01) what is definition of LED ?                                                                                                           Ans.(01)  light-emitting diode Ans ( 02 ) A  light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material .

( Ans) :       Definition of electricity .  (01) a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.                                                                   (02)    Electricity   is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
