Question

An electric current can produce

• A. heating effect only.
• B. chemical effect only.
• C. magnetic effect only
• D. chemical, heating, and magnetic effects

Answer 1

The correct option is D

chemical, heating, and magnetic effects

Explanation of correct option:

1. Electric current is defined as the rate of flow of electrons through a conductor
2. Its SI unit is Ampere($A$)
3. One ampere is the flowing of 1-coulomb charge through a conductor per unit time
4. There are different types of effects produced by electric current depending on through which substance it flows
5. The electric current s capable of producing heat, chemical and magnetic effect
6. If an electric current flows through a bulb, its filament heats up and glows.
7. From this case, we can say that electric current has a heating effect
8. If an electric current is passed through a molten solution, like it is done in electrolysis, there is a chemical change that occurs
9. In this case, we can say that the electric current has a chemical effect
10. If a metallic piece is wound with a wire and an electric current is passed through the wire, the metal piece acts as a magnet
11. This whole system is called a solenoid
12. Therefore we can say that the electric field has magnetic effects
13. From the points above, we conclude, that the correct option is option d)heat, chemical, and magnetic effects

Hence, option D is correct.
