Overview

Electrical energy is closely connected with electric charge, electric potential, current, resistance, and power. Charge can be transferred by rubbing, and that transfer explains static electricity. When charge moves through a conductor, electric current is produced. A cell supplies the potential dif

Key Concepts

The electricity or charge developed on

The electricity or charge developed on a body on rubbing with another body is called frictional electricity or static electricity. Rubbing does not cr

Two types of charge are produced

Two types of charge are produced on rubbing: positive and negative. A glass rod rubbed with silk acquires positive charge, while an ebonite rod rubbed

Conservation of charge states that

Conservation of charge states that the total amount of electric charge in an isolated system does not change with time.

According to Coulomb's law

According to Coulomb's law, the magnitude of the force between two point charges is directly proportional to the product of the charges and inversely

Electrostatic potential is the work done

Electrostatic potential is the work done in bringing a unit positive charge from infinity to a point. Potential difference is the work done in moving

Learning Objectives

  • Understand static electricity and the transfer of charge by rubbing
  • Distinguish between positive and negative charges and explain attraction and repulsion
  • Apply Coulomb's law for force between charges
  • Define electrostatic potential and potential difference
  • Understand electric current, conventional current, and the role of a cell
