What is heating effect of electric current?

Question

Answer

When electric current passes through a high resistance wire, the wire becomes and produces heat. This is called heating effect of current.

Answer

When electric current is supplied to a purely resistive conductor, the energy of electric current is dissipated entirely in the form of heat and as a result, resistor gets heated. The heating of resistor because of dissipation of electrical energy is commonly known as Heating Effect of Electric Current. Some examples are as follow:-

•When electric energy is supplied to an electric bulb, the filament gets heated because of which it gives light. The heating of electric bulb happens because of heating effect of electric current.

Answer

Heating effect of electric current means when an electric current is passes through a wire it generates heat

Answer

Heating Effect of Electric Current

Electric current flowing through a conductor causes the conductor to heat up due to the resistance it encounters. This phenomenon is known as the heating effect of electric current.

Explanation

- When an electric current passes through a conductor, the electrons collide with the atoms in the conductor, causing them to vibrate and generate heat.
- The amount of heat produced is directly proportional to the square of the current passing through the conductor and the resistance of the conductor.
- This heating effect is utilized in various devices such as electric heaters, toasters, and stoves where electricity is converted into heat energy for practical applications.
- The heating effect is also responsible for the glowing filament in an incandescent light bulb, where the high resistance of the filament causes it to heat up and emit light.

Applications

- Electric heaters: Electric current passing through a high-resistance wire in an electric heater generates heat to warm up a room or space.
- Toaster: The heating elements in a toaster utilize the heating effect of electric current to toast bread by converting electrical energy into heat.
- Electric stoves: The coils in an electric stove heat up when electricity passes through them, allowing for cooking or boiling of food.

In conclusion, the heating effect of electric current is a fundamental principle in the functioning of various electrical devices and is harnessed for practical applications in our daily lives.
