Conversion of Voltage Source into Current Source

Constant Current Source A voltage source that has a very huge internal*impedance as compared with external load impedance or resistance is known as a constant current source. In that case, the load current approximately remains the same when the output voltage changes. Fig. 1.12 (i) illustrates a constant current source. It is a direct current … Read more Conversion of Voltage Source into Current Source

Free Electrons | Voltage Source | Constant Voltage Source

The valence electrons of different materials have different energies. The larger the energy of a valence electron, the weaker it is bound to the nucleus. In some substances, particularly metals, the valence electrons possess huge energy that electrons are very loosely attached to the nucleus. These loosely attached valence electrons motion at random within the … Read more Free Electrons | Voltage Source | Constant Voltage Source

Electron | Energy of an Electron | Valence Electrons

Since electronics deals with small particles called electrons, these tiny particles require a more detailed study. As discussed before, an electron is a negatively charged particle having nearly zero mass. Some of the important most properties of an electron are : (i) Charge on an electron, e = 1.602 × 10−19 coulomb(ii) Mass of an … Read more Electron | Energy of an Electron | Valence Electrons

Atomic Structure |Structure of Elements

According to modern world theory, the matter is electrical in nature. All the materials are composed of very tiny particles called atoms. The atoms are the building bricks of all things in the visible world. An atom composed of a central nucleus of positive charge around which tiny negatively charged particles, called electrons revolve in … Read more Atomic Structure |Structure of Elements

What is Electronics? | Importance of Electronics

The branch of engineering science which deals with current conduction through a vacuum or gas or semiconductor called *electronics. Electronics essentially deals with electronic devices and their utilization.A device is that during which current flows through a vacuum or gas or semiconductor. Such devices have valuable properties that enable them to function and behave because … Read more What is Electronics? | Importance of Electronics
