If you want to understand resistor color coding then you are at right place where you are explained full resistor calculator depending upon the resistor colour bands which are always confusing for the electricians. There are 4, 5 and 6 bands on different resistors. How to Read Resistor Color Code? Resistors are color coded for… Read More »
LDR or Light Dependent Resistor which is also known as photo resistor is a device whose resistivity is a function of the incident electromagnetic radiation. SO we can say that these are light sensitive devices. Other terms which are used for LDR are photo conductors, photo conductive cells or simply photocells. Light dependent resistor (LDR) or… Read More »
Generally there are two power transmission and distribution systems that are used to transmit electrical energy i.e. HVDC or High Voltage Direct Current transmission system and HVAC or High Voltage Alternating Current transmission system. Now let’s see the advantages and disadvantages of both power distribution systems. COMPARISION OF HVAC & HVDC SYSTEMS HVAC transmission is… Read More »
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 Electricity? Electricity is a form of energy that can be easily changed to other forms. Electricity comes mainly from 2 sources i.e. Power stations and generators that supply a lot of electricity and normally used in many electrical appliances and industrial applications. From Electric Cells or batteries which are used for portable purposes. To… Read More »
