Mir NAND gate is the most important logic gate in digital electronics and integrated circuits. IC7400 is a popular IC that consists of 4 NAND gates. The biggest importance of NAND gate is that it is one of the universal logic gates using which other logic gates can be implemented. Construction of basic logic gates using … Read more
In another article, we discussed the tension of a string or rope. We found that the tension of a string is a kind of force. Again, we know that a body can move due to the application of external force. So, the work done on a body depends on the force acting on it. Then, … Read more
If you drop a ball from the roof of your house, the ball will fall under gravitational force. Now, attach the ball to an end of a string and fix the other end of the string somewhere on the roof. Then drop the ball from the roof again. This time the ball will be hanging … Read more
Earlier we have written on intrinsic and extrinsic semiconductors. There are two types of extrinsic semiconductors – n-type and p-type. We already have discussed n type semiconductor materials in another article. In this article, we are going to discuss p type semiconductor material, its formation, properties, examples and uses. One can differentiate n-type and p-type … Read more
Impurity mixed semiconductors are known as the extrinsic semiconductors. Now, there are two types of extrinsic semiconductors. These are n type and p type semiconductors. They have different properties and the ways of formation are also different. We already have discussed p type semiconductors in another article. In this article, we are going to discuss … Read more
Capacitor is an important component in an electrical circuit which can store electric charges. We have discussed different types of capacitors in other articles. Like other components (resistors, inductors), a capacitor also offers opposition to the current flow through it. That means it generates impedance. Ohm’s law tells us that an impedance causes a voltage … Read more
We already discussed mechanical energy in the previous article. There are two types of mechanical energy – Kinetic energy and potential energy. Kinetic energy also has two types – translational kinetic energy and rotational kinetic energy. We already have an article on rotational kinetic energy. In this article, I’m going to share the basic differences … Read more
We discussed the kinetic energy of an object and the related facts. A body can have two types of kinetic energies – Translational kinetic energy and Rotational kinetic energy. In this article, we are going to be more specific. Here, we are to explain the rotational kinetic energy i.e. the kinetic energy due to the … Read more
Electrical components like resistors, capacitors, inductors and their combination offer an electrical impedance to the current flow. Ohm’s law gives an expression for the impedance (resistance) of a resistor in terms of current and voltage. But how to find the impedance of an inductor? In this article, I will explore the formula for the impedance … Read more
We know that the opposition to the current flow through a conductor is called resistance. Impedance is almost the same as resistance, but with a slightly different concept. In this article, we are going to discuss the definition, units and formula for impedance in different electronic circuits. The impedances of a pure resistor, pure capacitor, … Read more
