What is Raspberry Pi? Raspberry PI is the name of a series of single-board computers made by the Raspberry PI  Foundation, a UK charity that aims to educate people in computing and create easier access to computing education. The Raspberry PI  launched in 2012, and there have been several iterations and variations released since then. T

What is Diode:   A Diode is defined as a two-terminal electronic component that only conducts current in one direction (as long as it is operated within a specified voltage level). An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. It’s an important part of any electrical or ele

Doping   Doping is the process in which impurities are added to a semiconductor to change/control it’s electrical properties. The semiconductor in which impurities are added is called extrinsic semiconductor.   Doping is done in semiconductors for three main reasons:   * Change the conductivity of the material. * To prod

CONDUCTORS Any material which allows current to flow is called a conductor. Metals are a good conductor of electricity. An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such a

Introduction to ohm's law Georg Simon Ohm was born in 1787 in Erlangen, Germany. He taught mathematics in local schools and performed experiments in physics, trying to master the principles behind electromagnetism. Later, in 1826, he published papers on the way circuits conducted heat in Fourier's studies. In May 1827, Ohm described the relations

RESISTORS In the manufacturing of electronic equipment resistors of all types are used in large quantities. Resistor is probably the most common type of electronic component used in electrical and electronic circuits. Many different types of resistors are available. The properties of these different resistors vary, and it helps to obtain the ri

DIODES Introduction to Diode A diode is defined as a two-terminal electronic component that only conducts current in one direction (as long as it is operated within a specified voltage level). An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. A diode is an electrical device that allows cu

What is Mesh/Loop? Any close path in which electrical current can flow is known as a mesh or loop. What is  Mesh Analysis? Mesh Analysis is applied when more than one voltage source is given in a circuit. If current sources are given, at first all current sources have to be converted into voltage sources to apply Mesh Analysis. Mesh Analy

 Kirchhoff’s Circuit Law   In 1845, a German physicist, Gustav Kirchhoff developed a pair or set of rules or laws which deals with the conservation of current and energy within electrical circuits. These two rules are commonly known as Kirchhoff’s Circuit Laws with one of Kirchhoff’s law dealing with the current

Learning Objectives of Nodal Analysis a. Apply Ohm’s law using nodal voltages.  b. Apply the nodal analysis method to determine multiple unknown node voltages and branch currents in a simple dc circuit. What is Nodal Analysis? Nodal analysis is a method of analyzing circuits based on defining node voltages as the varia
