Study Notes
Electric Charge
- Charge is a property of a substance.
- It allows substances to exert electric forces or respond to electric fields.
- The unit of charge is Coulomb (C).
- Charge can be positive or negative.
Quantization of Charge
- A charge is always a whole number multiple of the elementary charge.
- Charge cannot be a decimal.
- Possible charges are (+1e, +2e, +3e...).
- Impossible charges are (+0.5e, +1/3e, +5/7e...).
Superposition Principle
- The net force on a charged particle due to other charges is equal to the vector sum of the forces exerted by each individual charge.
- This principle is used to calculate the net force on a particle within a system of charged particles.
