Applications of heating effect of current
- The heating effect of current is utilized in the electrical heating appliances for example electric iron, room heaters, water heaters etc.
- The heating effect of electric current is utilized in electric bulbs or electric lamps for producing light.
- An electric fuse is an important application of the heating effect of current. The working principle of a fuse wire is based on the heating effect of current. When high current flow through the fuse (current higher than the rated value) then the heat developed in the wire melts it and breaks the circuit.
- In an electric heater one type of coil is used. A high resistance material like nichrome or same type of material is used as coil. The coil is wound in grooves on ceramic format or china clay. Flowing electric current through the coil it becomes heated. Due to high resistance the coil becomes red color forms.
