CLASS 10 ELECTRICITY MCQ
The concept of electricity came into notice due to friction. It actually proves that charges can be produced and they can also be made to flow and flowing of charges gives rise to electricity. So let us first learn about friction
Friction
It comes into notice when two bodies are rubbed with each other.
For example: Rubbing of a glass rod with silk. When a glass rod is rubbed with silk, electrons move from glass rod to silk therefore, the glass rod acquires a positive charge as it becomes deficient of electrons and silk will acquire negative charge as the amount of negative charge in it increases.
So, due to this concept of friction, the concept of charges came in to notice. And further, coulomb was the one who gave more information about the charges.
