Electrostatics of Conductors – Class 12 | Chapter – 2 | Physics Short Notes Series PDF for NEET & JEE

Electrostatics of Conductors: Electrostatics of conductors refers to the study of the behavior of electric charges on the surface and inside of conductors. Conductors are materials that allow electric charges to flow freely through them, and as a result, they have some important properties that are useful in many applications. The main property of conductors is that they have no electric field inside them. This means that the electric potential inside a conductor is constant and equal to the electric potential on its surface. This property makes conductors ideal for storing and transporting electric charges, as the electric potential inside a conductor is not affected by the presence of electric charges.

Properties of Electrostatics of Conductors

The properties of electrostatics of conductors can be summarized as follows:

  • No electric field inside: Conductors have no electric field inside, which means that the electric potential inside a conductor is constant and equal to the electric potential on its surface.
  • Even distribution of charges: Conductors distribute electric charges evenly on their surface. This is because charges will naturally flow to the surface of a conductor to minimize their potential energy.
  • Shielding against electric fields: Conductors can be used to shield against electric fields. Because electric fields do not penetrate inside conductors, they can be used to protect sensitive electrical equipment from external electric fields.
  • Storage and transportation of electric charges: Conductors are ideal for storing and transporting electric charges, as the electric potential inside a conductor is not affected by the presence of electric charges.
  • Creation of uniform electric fields: Conductors can be used to create uniform electric fields, which are important in many applications such as electric motors, generators, and transformers.
  • Electrically neutral: A conductor is electrically neutral when it has an equal amount of positive and negative charges. When a conductor is charged, it will redistribute the charges so that the surface potential remains constant.
  • Ideal for electrical grounding: Conductors are ideal for electrical grounding, as they allow electric charges to flow to the ground and neutralize any electric fields that might be present.
