Study Notes
Properties of Charge
- Charge is a scalar quantity.
- Charge is additive, meaning the total charge of a system is the sum of the individual charges.
Quantisation of Charge
- Charge is quantized, meaning it comes in discrete packets (quanta).
- The charge on a body is an integer multiple of the charge on an electron (e).
- The total charge on a system is given by the algebraic sum of the charges (with signs).
Conservation of Charge
- The total amount of charge on an isolated system is conserved.
- Charge cannot be created or destroyed, only transferred from one body to another.
Electronic Charge
- The magnitude of the electronic charge (e) is 1.6 × 10^-19 C.
- The charge on an electron is -e, while the charge on a proton is +e.
Units and Measurements
- The unit of charge is the coulomb (C).
- The mass of an electron is 9.1 × 10^-31 kg, while the mass of a proton is 1.6 × 10^-27 kg.
Types of Charge
- There are two types of charge: positive and negative.
- A body with no net charge is said to be neutral.
- A body with an equal number of positive and negative charges is also neutral.
