Working Principle of Relay. It works on the principle of an electromagnetic attraction. When the circuit of the relay senses the fault current, it energises the electromagnetic field which produces the temporary magnetic field. This magnetic field moves the relay armature for opening or closing the connections.
· Working of LED. Like an ordinary diode, the LED diode works when it is forward biased. In this case, the n-type semiconductor is heavily doped than the p-type forming the p-n junction. When it is forward biased, the potential barrier gets reduced and the electrons and holes combine at the depletion layer (or active layer), light or photons are.
· The underlying principle of any hydraulic system
· The hybrid system in 's SK-80H-2 excavator (developed for the Japanese market in ) is distinctive in that it combines both electric and hydraulic aspects. The system uses an engine-driven generator to charge both a capacitor and a nickel-metal hydride battery via a converter. Stored power is directed through inverters to four.

· Working principle of wheel loader. Power system: The original power of the loader is generally provided by the diesel engine. The diesel engine has the characteristics of reliable operation, hard power characteristic curve and fuel economy, which meets the requirements of the loader's harsh working conditions and variable loads.
Transfer Function Of Synchros: The term synchro is a generic name for a family of inductive devices which works on the principle of a rotating transformer (Induction motor). The trade names for synchros are Selsyn, Autosyn and Telesyn. Basically, they are electro-mechanical devices or electromagnetic transducers which produces an output voltage.
Aiming to study the working efficiency and stability of the loader, the hydraulic system of the loader is studied. Taking the ZL50 loader as the research carrier, the working conditions of the loader and the working principle of the hydraulic system are analysed at first. AEMSim software is used to simulate and analyse the hy-draulic.
The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field.

Taking stage loader used in coal storage yard as an example, we introduce the mechanical structure and working principle of stage loader, mainly discuss about the components of electric control system, the action sequence of the actuator, electrical control PLC.
· The refrigeration system cool down the air which include many other parts like compressor,condenser etc. The air circulating system circulate this cooled air into the car which include blower, air duct etc.The controlling system used to control the temperature of the car by sensing it and control the refrigerating system.
· Introduction and Working Principle: The controlled movement of parts or a controlled application of force is a common requirement in the industries. These operations are performed mainly by using electrical machines or diesel, petrol and steam engines as a prime mover.
electrical systems for an existing building, then the electrical designer works to incorporate all the new electrical wiring into the existing system. The de-signer must evaluate the existing electrical system to ensure that existing electrical systems can accom-modate new additional electrical loads that will be imposed on them.
The main principle behind the working of such a regulator is that a large proportion of the change in supply or input voltage appears across the transistor and thus the utput voltage tends to remain constant. The output voltage can thus be written as. Vout = Vzener
