Based on the flow of charge, the electric current is classified into two types, i.e. alternating current (AC) and direct current (DC) AC Current The flow of electric charge in a periodically reverse direction is known as alternating current (AC). AC is also referred to as “AC Current”. Although this is technically saying the same …
What is battery? A battery, in a sense, can be any device that stores energy in the form of chemical energy. At the same time the battery converts electrical energy into chemical energy during charging and chemical energy into electrical energy during discharge. The common use of the term “battery,” however, is limited to the …
Coulomb’s law, or Coulomb’s inverse-square law is a law of physics that describes force interacting between static electrically charged particles. Consider two positive charges q1 and q2, separated by a distance r. the force interaction between the charges is directionally proportional to the magnitude of charges and the inversely proportional to the square of the …

Electricity is a very important factor in our lives. It is widely used for home purposes such as home lighting, computer, television etc. is concerned with the study of electrical charges. We know that the basic building blocks of matter are atoms and that all atoms are put together to form molecules. Naturally, an atom …
