What is a Transistor The transistor is a three-layer semiconductor device that consists of: two n-type layers and one p-type layer of material which is called npn transistor two p-type layers and one n- type layer of material which is called an pnp transistor There are two basic types of transistors i.e.bipolar junction transistor or… Read More »
Before discussing the types and importance of busbar protections let’s see what is a bus bar? The word bus is derived from Latin word “OMNIBUS” that means common for all, so busbar is actually a common and main part of a power distribution system that serves as nerve center of the power system where various… Read More »
What is a Diode? Di+Ode is a semiconductor device with two terminals allowing the flow of current in one direction only, diodes are made up of Silicon, Germanium & GaAs. The perfect diode would be a perfect conductor in one direction (forward bias) and a perfect insulator in the other direction (reverse bias). In many situations, using… Read More »
What is the Wheatstone Bridge? The Wheatstone Bridge consists of a dc voltage source, four resistors and a detector. The detector is a type of ammeter called a galvanometer. The galvanometer is used to detect the condition ig = 0 .When the circuit satisfies this condition we say that “the bridge is balanced”. A Wheatstone bridge… Read More »
We all have heard about the binary numbers and binary coded decimals and we also know that these are used inside the computers for the computation and processing of our commands. In digital electronics study students mostly as this question that What is BCD? In computer & electronics Binary Coded Decimal or BCD is a class of… Read More »
Gray Code is one of the most important codes. It is a non-weighted code which belongs to a class of codes called minimum change codes. In this codes while traversing from one step to another step only one bit in the code group changes. In case of Gray Code two adjacent code numbers differs from… Read More »
