Answer 1

Explanation:

The reason behind the heating effect of electric current is when the current passes through a conductor the electrons have to face the resistance of the conductor which results in the loss of energy and this loss of energy gets converted into heat energy.

Formula : H=I

RT

I= current

R= Resistance

τ= Time for which current traveled through the resistor.

Answer 2

VALID ANSWER

1. When an electric current passes through a wire, the electrical energy is converted to heat.

2. In heating appliances, the heating element is made up of materials with high melting point. An example of such a material is nichrome (an alloy of nickel, iron and chromium).

3. The heating effect of electric current has many practical applications.

4. The electric bulb, geyser, iron box, immersible water heater are based on this effect.  

5. These appliances have heating coils of high resistance.  

6. Generation of heat due to electric current is known as the heating effect of electricity.
