In electrical machines and instruments, an excitation system is the one which receives electrical energy to produce the working magnetic flux. The excitation system is the crucial component every electromechanical energy conversion device such as electric motor. Depending upon the number of input supplies, any electromechanical energy conversion system can ... Read More

Both turbocharger and supercharger are used to increase the pressure of atmospheric air before sending it to the engine cylinder. The compressed air increases the amount of fuel to enter into the engine cylinder for combustion, which in turn increases the power of the engine.Basically both turbocharger and supercharger perform ...

Sensors and transducers are extensively used in the electrical and electronic instruments to measure different physical quantities. However, there are many differences between a sensor and a transducer that we will discuss in this article. But, before getting into the differences, let's get an overview of what sensors and transducers ... Read More

A cell is an active circuit component that supplies electrical energy to the circuit. A cell stores the energy in the form of chemical energy and converts it into electrical energy when the load is connected across its terminals. Depending on the ability to recharge, the cells are classified into ... Read More

A turbine is a device which converts the energy of some fluid into rotational mechanical energy. There are a number of turbines available based on the type of input used such as steam turbine, water turbine, gas turbines, etc.The most commonly used water turbines are Pelton wheel, Francis turbine and ...
