Electric Charge, Law of Charges, and Quantization of Charge

The video tutorial explores the concept of electric charge through demonstrations with balloons and rods. It explains the law of charges, which states that unlike charges attract and like charges repel. The tutorial delves into the nature of charge, discussing electrons and protons, and introduces the concept of elementary charge. It also covers the quantization of charge, emphasizing that charge comes in discrete quantities. The video concludes with practical examples illustrating these principles.

What is the elementary charge and why is it significant?

What is the role of quarks in the composition of protons?

How many excess protons are needed to achieve a charge of 1 Coulomb?

Explain why charge is considered quantized.
