Class 7 Physics Electric Current and its Effects Heating Effects of Current

Heating Effects of Current

When electric current is passed through a conductor, it generates heat due to the resistance it offers to the current flow.

  • Appliances which require heating effect have conductors or the heating elements.
  • Heating elements have high melting point so that they do not get damaged due to the heat generated.
  • These elements have also low tendency to react with oxygen to avoid catching fire.
  • The amount of heat generated in a wire depends upon
    • Material of the wire
    • Length of the wire
    • Thickness of the wire
