The heating effect of electric current is a phenomenon in which heat energy is generated in a conductor when an electric current flows through it. The amount of heat produced depends on three factors:
- The amount of current flowing through the conductor
- The resistance of the conductor
- The time for which the current flows through the conductor
The heat produced by an electric current, I, through a conductor of resistance, R, for a time, t, is given by the Joule’s equation of electrical heating, which is H = I^2Rt.
The heating effect of electric current has several applications in our daily lives, such as:
- Electric heaters
- Electric irons
- Electric toasters
- Electric ovens
- Electric kettles
These appliances utilize the heating effect of electric current to produce heat.
In summary, the heating effect of electric current is the production of heat energy in a conductor when an electric current flows through it. The amount of heat produced depends on the current flowing through the conductor, the resistance of the conductor, and the time for which the current flows through the conductor. This phenomenon has several applications in our daily lives, such as electric heaters, irons, toasters, ovens, and kettles.
