Write properties of conductor by Fast2study

PROPERTIES OF CONDUCTOR

• The charge density inside the conductor is zero.
• An electrical conductor is an electric charge carrier.  Conductivity is the ability to transmit electricity or heat. Good conductors are copper, gold, steel, aluminium, brass etc.
• The flow of electrons in a conductor is known as the electric current. The force that is required to make that current flow through the conductor is known as voltage.
• Conductors are materials which contains large number of free electrons which can move freely inside the conductor therefore net electric field inside a conductor in electrostatic condition is zero.
• In electrostatics conductors are always equipotential
• surfaces.
• Charge always resides on outer surface of conductor.
• If there is a cavity inside the conductor having no charge then charge will always reside only on outer surface of conductor.
• Also Read:
  • Force on a Dielectric in a Capacitor.
  • What is Coulomb’s Law and some related important point.
  • What is charge and also described properties of charge.
  • Define and Explain Radioactive Element and Radioactivity
• Electric field is always perpendicular to conducting surface.
• Electric lines of force never enter into conductors.
• Electric field intensity near the conducting surface is given by formula.
• 
• When a conductor is grounded its potential becomes zero.
• When an isolated conductor is grounded then its charge become zero.
• When two conductors are connected there will be charge flow till their potential becomes equal.
• As surface of conductor is equipotential therefore the Surface charge density  of conductor at that 1S point. of conductor is inversely proportional to the radius of curvature at that point.
• Electric pressure: Electric pressure at that aur face of a conductor is given by formula.

Where σ is the local surface charge density.
