Study Notes
Definition of Electricity
- Refers to the physical phenomena associated with the presence and movement of electric charge.
- Includes various effects such as lightning, static electricity, and the operation of electrical devices.
Benjamin Franklin's Contribution
- Conducted experiments in the mid-1700s to explore the nature of electricity.
- Proposed that electricity consisted of two types of charges: positive and negative.
- Suggested that lightning is a form of electrical discharge.
SI Unit of Electric Current
- The standard unit is the ampere (A).
- Represents the flow of electric charge and indicates how much charge passes through a conductor in a given time.
Movement of Charge
- Known as electric current.
- Involves the flow of electrons or other charged particles through a medium.
Assumption by Benjamin Franklin
- Assumed that electric current flows from positive to negative.
- This assumption established the conventional current direction, which is still used in circuit analysis today.
