Question

An electric current can produce

  1. Magnetic effect
  2. Heating effect
  3. Chemical effect
  4. Chemical, heating, and magnetic effects

hintHint:

The electrical current produces a chemical, heat, and magnetic effects.

The correct answer is: Chemical, heating, and magnetic effects


    • The electric current is a flow of electrons through the conductor.
    • It converts chemical or mechanical energy into various forms.
    • Electrical energy produces a chemical, heating, and magnetic effects.
