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
