This article covers, the difference between Zener breakdown and Avalanche breakdown. The major difference between Zener breakdown and Avalanche breakdown is Zener breakdown occurs because of strong electric field. Avalanche breakdown occurs because of the collision of electrons. A diode is used in electronic circuit to allow the flow of current in only one direction. … Read more
This article contains Resistor colour coding experiment. Lab Work. There are 5 given resistors as sample & we need to find its value, by reading colour bands on it. Aim of the experiment Resistor colour coding Objective To learn resistor colour coding. To determine the stated value of a resistor by interpreting the colour code … Read more
A Bipolar junction Transistor has three semiconductor regions that are doped at different levels. Out of three regions two of them are doped with either donor or acceptor atoms and the third region is doped with other atom. In case of NPN transistor, two regions are doped with donor impurity and the other regions is … Read more
In this article, we will discuss about semiconductors and its types. Intrinsic semiconductor and extrinsic semiconductor. What is a semiconductor ? A semiconductor can be defined as aa material whose electrical conductivity lies between conductor and insulator. The electrical conductivity of conductor > semiconductor > insulator. Some examples of semiconductor are silicon and germanium, they … Read more
The Wheatstone bridge or the resistance bridge is the special arrangement of resistors that is used to calculate the unknown resistance by balancing of bridge circuit. It was discovered by Charles Wheatstone. Wheatstone bridge circuit Construction The bridge contains four resistances out of which the value of two resistances are known. The third one is … Read more
A short theoritical explanation of ferranti effect by freak engineer for beginners. Know why ferranti effect occurs and how to reduce it.
Students often get confused when they are asked to differentiate between alternating current and direct current. This blog covers 20 difference between ac and dc. Electrical current flows in two ways, it either flows in single direction or reverses its direction periodically. When electrical current flows in single direction it is known as Direct Current … Read more
In this article we will cover Metal Oxide Varistor its specifications, graph, connections and applications. A Varistor is an electronic component that protects electronics devices from over voltage by the concept of voltage clamping. The word varistor can be stated as variable resistor or a voltage dependent resistor. Its resistance cannot be varied manually like … Read more
Resistor Value Calculation for LED In this blog I am going teach you calculation for the value of resistor that is used in the protection of led. Currently LED’s ( Light Emitting Diodes ) are used for wide range of purpose mainly as indicators. Light emitting diodes are very sensitive. They easily get blown off … Read more
This blog is about battery charging time calculation. The same formula can be used to calculate battery discharge time. I will let you know a basic formula with some examples. Battery Charging Time Battery charging time ( hour ) = Battery capacity ( In Ah ) / Current supplied ( In A ) Using this … Read more
