MCQ
Electric energy is produced by the:
- ✓Separation of charges.
- BSeparation of protons.
- CSeparation of holes.
- DSeparation of plates.
✓
Answer
Correct option: A.
Separation of charges.
Electric energy is a form of energy, which is created by the movement of electrons. Generally electrons are bound to an atom by the positive force of protons. When for some reason these electrons get detached from their atoms electric energy is produced.
