Electric Charge, Law of Charges, and Quantization of Charge (12:12)
The Law of Charges is demonstrated using a rubber balloon suspended from the ceiling. The net charge on an object via excess protons and electrons. Quarks as the constituent of protons and neutrons. Quantization of charge is mathematically demonstrated. This is an AP Physics 1 Topic.
