Electricity

It is a form of energy resulting from the presence and flow of electric charge. It is a fundamental part of nature and one of the most widely used forms of energy.

Basic Concepts

  1. Electric Charge:

    • Exists in two types: positive and negative.

    • Like charges repel each other, and unlike charges attract.

  2. Electric Current:

    • Flow of electric charge, typically measured in amperes (A).

    • Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically.
