Hello, friends, I hope all of you are having fun in your life. In today’s tutorial, we will explain what an ammeter is. In 1820 Hans Christian Ørsted, who belonged to Denmark, discovered the relationship between current, magnetic field and physical forces (gravitation, electromagnetism, weak interaction, and strong interaction). He performed an experiment for this…

Hello, friends, I hope all of you are having fun in your life. In today’s tutorial, we will explain what a PN junction is. The PN junction is a line between 2 different categories of semiconductors; it forms when we dope any semiconductor material with a doping element. If we doped any silicon crystal with…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the difference between N- and P-type semiconductors. Semiconductor substances are materials that have conductivity properties between conductors and insulators. Their conductance is restricted due to the small number of free electrons and holes in the valence…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the conductivity of semiconductors. The number of electrons present in any substance defines the conductance of that material. Elements that show a high value of conductance has a large number of electrons, such as conductors. While…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the difference between conductor, insulator, and semiconductor. There are 3 types of material according to their electric behavior and features. The first one is an insulator, the second one is the conductor, and the third one is…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the Commutation and Armature Construction in Real DC Machines. In DC machines there are many methods to join armature windings with the commutators. These methods of connection define the no of parallel paths for current in…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss commutation in a four-loop DC machine. The voltage generated at the output terminals of DC machines is pure AC voltage. To convert these voltages into DC voltage, commutators are introduced at the terminals that convert the…

Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the Simple Rotating Loop between Curved Pole Faces. There are two main types of DC machines. The first is a DC motor, and the second is a DC generator that produces electrical power through mechanical energy,…
