Types of Electric Current

Electrical current is the flow of charged particles. It is similar to flow of water molecules in a river. Electric current is of two types:

  1. Direct Current (DC)
  2. Alternative Current (AC)

Direct Current: (DC):

In this type of electric current, direction is always same. The electric current generated from a cell or battery is DC. Due to the same direction …

Basic Electronics Definition | What is Electronics

Electronics is science of controlled activities or movement of free electrons present in Atom of a matter.
The first electronic component every made in 1906 was triod or triode.

Triode - A triode is an electronic amplification device having three active electrodes.

Electronics is used in factories, at home, in medical field, defense etc.

Electronic Components:

All electronic components are divided into two categories:

  • Active Devices
  • Passive Devices

Active devices or components …

Potential Difference

What is Potential Difference?

Potential difference can be simply defined as the difference of electrical potential between two points. When two positive charges when brought close to each other, they repel. When two negative charges are brought close to each other, they also repel. But when a positive and a negative charge brought close together, they attract each other. When …

Electric Current

What is Electric Current?

Electric current is the flow of electric charge (charged particles) through a conductor with respect to time. The process is similar to flowing of a river in one direction. Electric current is measured by the number of “free electrons” passing a particular point in a circuit per second. So we can conclude and define electric current …

Structure of an Atom

During our school days, we all studied in science that atoms are made up of 3 particles – electrons, protons, and neutrons. The arrangement of electrons and protons are different in different elements. We also learnt that electrons are negatively charged (-) and revolve around the nucleus of the atom in concentric paths called orbits. Protons are …
