The heating effect of electric current is a phenomenon where an electric current flowing through a conductor generates heat due to the resistance offered by the conductor to the flowing current. The work done in overcoming this resistance generates heat in the conductor. The heating effect of electric current is widely used in our day-to-day life. Following are some applications of the heating effect of electric current:

• Electric Iron: The heating element in an electric iron is made of a material that has high resistance and can withstand high temperatures. When an electric current flows through the heating element, it generates heat, which is used to press clothes.

• Electric Heater: An electric heater works on the principle of the heating effect of electric current. The heating element in an electric heater is made of a material that has high resistance and can withstand high temperatures. When an electric current flows through the heating element, it generates heat, which is used to warm up a room.

• Electric Kettle: An electric kettle works on the principle of the heating effect of electric current. The heating element in an electric kettle is made of a material that has high resistance and can withstand high temperatures. When an electric current flows through the heating element, it generates heat, which is used to boil water.

• Electric Oven: An electric oven works on the principle of the heating effect of electric current. The heating element in an electric oven is made of a material that has high resistance and can withstand high temperatures. When an electric current flows through the heating element, it generates heat, which is used to cook food.

The heating effect of electric current is given by the Joule’s equation of electrical heating, which states that the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I^2Rt.
