Conductivity of a Semiconductor – formula

In the first two articles on Semiconductors, we have discussed the basic properties, examples, types and applications of semiconductor materials. We became to know that Semiconductors have conductivity greater than insulators but well less than conductors. So, semiconductors are not excellent conductors of electricity. That means a pure semiconductor is not suitable for conducting current … Read more

7 Types of Logic Gates with their diagrams

A digital computer uses logic gates to perform various logical operations. Do you know how many logic gates are there? There are seven logic gates in digital electronics. Now, what are the seven logic gates? This animation explores all 7 types of logic gates with their diagrams. Watch this – Hope this animation file helped … Read more

Types of Breakdown in diode and their causes

A p-n junction diode works properly in forward bias condition. Because, a higher amount of current flows for this biasing condition. On the other hand, a very small amount of current flows through the diode when it is connected to a reverse bias. Again, a higher amount of reverse bias voltage can create a breakdown … Read more

Advantages and Disadvantages of Solar Energy

Solar energy is a trending topic of science in recent times. The non-renewable sources of energy are about to extinct due to their limited storage on the Earth. Therefore, alternative sources of energy are needed to fulfill our daily needs of energy. There are some renewable sources of energy like Solar energy, Wind energy, Geothermal … Read more

NOT AND OR gate using NAND gate – circuit diagram

Earlier we have discussed the basic logic gates with truth table, circuit diagram and Boolean expression. The three basic logic gates in Computer are OR gate, AND gate and NOT gate. The universal logic gates like NAND gate and NOR gate are also introduced with you. All logical gates can be designed by using universal … Read more

XNOR gate circuit diagram using NAND & NOR gate

XNOR gate is another logical gate that is available in integrated circuit (IC) form. In other articles, we have discussed that NAND gate and XOR gate are also available in IC form. Therefore, these types of logic gates are very much useful in advanced digital electronics. Basic logic gates (OR gate, AND gate and NOT … Read more

Karnaugh map for simplification of Boolean expression

Karnaugh map is a very useful tool for simplification of Boolean expression in digital electronics. The other name of Karnaugh map is K-map or K map. It can represent the Boolean equation both in sum of products (SOP) form and product of sum (POS) form. There are two ways to simplify Boolean expressions. One is … Read more

Rules of Boolean algebra for simplification

Boolean algebra is a very useful method for simplification of binary expressions. There is no connection between the general algebra we know and the Boolean algebra. Boolean algebra deals with the binary bits only. There are different laws of Boolean algebra to simplify the Boolean expressions. In this article, we are going to discuss all … Read more

NOR gate truth table with 2 and 3 inputs

NOR gate is one of the universal logic gates along with the NAND gate. Do you know how to make NOR gate? How does NOR gate work? One can make a NOR gate by connecting an OR gate and a NOT gate in series. So, the main work of a NOR gate is to give … Read more
