Question

Which effect of electric current is utilized in a electric iron

Answer 1

Answer:

Heating effect is the effect that is used in electric iron .

Explanation:

Electric current

1. It is the rate of flow of charge through any conductor .
2. It is denoted by "I".
3. Its expression is : I=q/t
4. Its S.I unit is Ampere .

Electric current can produce many effects like :

• Magnetic effect
• Heating effect

Magnetic effect : Is produced when current carrying wire is placed between poles of magnet .In this case we get to see the magnetism ,without the presence of magnet .

Heating effect : It is produced when the electrons in wire move , they collide with one another and also with the walls of conductor and produce heat .This is heating effect produced as a result of collisions .
