A lot of engineering projects & tutorials for engineering students to help them in their final year projects.

What is Star Delta Transformation


Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Star Delta Transformation. In electrical and electronic systems the different circuits are joined in parallel and series combinations. Such circuits can be solved by using series and parallel formulas of resistances. But in case of complicated circuitries these […]

What is Bypass Diode


Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Bypass Diode. Bypass diode is used in photovoltaic modules. The main purpose of the diode in photovoltaic modules is to reduce the hot-spot (It is a heating phenomena that occurs when the photovoltaic cells are joined in a sequence […]

What is the Voltage Source


Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is the Voltage Source. The source is a device that transformed thermal energy, chemical energy, mechanical energy or any type of energy in the electrical form of energy. We can say that the source is such an instrument manufactured […]

What is Magnetic Hysteresis


Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Magnetic Hysteresis. Hysteresis occurs in different substances due to the 2 different factors first one is magnetization of the material and second is the variation in the quantity of the magnetic domains of the material (it is the part […]

Transistor as a Switch


Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Transistor as a Switch. The transistor is a 3 pin semiconductor module used for different amplifier and switching circuits. It was created by William Shockley (who was a physicist of United States of America) in 1947. It also […]

What is Inductance


Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Inductance. In 1886 first time in the world the word inductance was used by the English scientist Oliver Heaviside. The symbol for the inductance is L that was indicated due to the scientist Heinrich Lenz who gave famous Lenz’s […]
