Photodiodes and Phototransistors are both semiconductor electronic devices that convert optical energy into electrical energy. Therefore, due to their similar function, one may get confused between these two devices. Both photodiode and phototransistor sense the light from a source and generate an electric signal having the strength corresponding to intensity ... Read More

A machine which consists of moving parts and converts one or more form of energy into mechanical energy (usually in the form of motion) is known as an engine. Depending on the fuel used as the source of energy, the engine may be classified in following the types − ... Read More

In electromagnetism, permeance and reluctance are the two major quantities related to magnetic circuits. Both permeance and reluctance provide information about the ease and opposition in the flow of magnetic flux offered by the core material of the magnetic circuit. Where, the reluctance is the measure of opposition in the ... Read More

LVDT and RVDT are types of passive transducers that convert displacement into an electric signal. Both LVDT and RVDT are types of inductive transducers and their construction is just like a transformer. In this article, we will highlight all the differences between LVDT and RVDT. Let's start with some ... Read More

LED and Photodiode are both semiconductor-based electronic devices that function by the interaction of light energy and electricity. LED converts the electricity into light, whereas a photodiode converts the light energy into electricity. Therefore, LEDs and photodiodes are quite different in the way they operate. In this article, we ... Read More

Both transformers and induction motor both are the most extensively used electrical machines in practice. The transformer is an electromagnetic static machine while the induction motor is an electromechanical energy conversion device. Since the induction motor and transformer are functionally quite similar because both work on the Faraday’s law of ... Read More

Heating is a process of increasing the temperature of a body at an acceptable level by using thermal energy. The mechanism involved in heating is generally referred as a heating system. When the process of heating is performed by using the electric current, i.e. the electric current is converted into ... Read More

A Wind Turbine is a device which uses kinetic energy of blowing wind to generate electrical energy. A wind turbine consists of two or three rotor blades which are mounted on a rotor. When the blowing wind exerts a lift and drag force on these blades, the rotor starts rotating. ... Read More

A magnetic material is a type of substance or material which gets attracted towards a magnet. The magnetic material also acquires magnetization when it is placed in the magnetic field of a magnet. Depending on the magnetization property, there are two types of magnetic materials namely, Hard Magnetic Materials ... Read More
