Study Notes
Electricity Basics
- Benjamin Franklin is credited with introducing the terms 'positive' and 'negative' to describe two distinct types of electricity.
- The study of charges when they are not moving is referred to as electrostatics.
- The term 'electricity' originates from the Greek word "ēlektron", meaning amber.
- The basic characteristic of matter that causes electrical processes is the presence of charged particles, such as electrons and protons.
- Benjamin Franklin used a kite to collect electricity from stormy clouds.
- The unit charge of electrons is -1.6 x 10^-19 C.
- Benjamin Franklin experimented with charges in the 18th century.
- The two opposing unit charges found in most materials are positive (protons) and negative (electrons).
- A neutral atom has a balance of electrons and protons, with the number of electrons equal to the number of protons.
Alternative Terms
- Electrostatics is also known as static electricity.
