Study Notes
### Fundamental Unit of Charge
- The fundamental unit of electric charge is the coulomb (C).
- One coulomb is a large unit of charge.
- The charge of a single electron is approximately -1.602 x 10^-19 C.
Proton Charge
- Protons always carry a positive charge.
Electric Charge and Electric Field
- An electric field is created by an electric charge.
- Electric fields exert forces on other charges.
- The direction of the electric field is defined as the direction of the force on a positive test charge placed in the field.
Conservation of Electric Charge
- The principle of charge conservation states that the total electric charge within an isolated system remains constant.
- This means that charge cannot be created or destroyed.
Direction of Electric Current
- The direction of electric current is conventionally defined as the direction of positive charge flow.
- However, in many materials (such as metals), it is the negative charge carriers (electrons) that actually move.
