Study Notes
- Electricity is the flow of electric current or electrons.
- It can be transformed into other forms of energy like heat, light, and mechanical energy.
- The flow of electricity through an object is known as current, measured in amps.
- Voltage is the driving force behind the flow of current, measured in volts.
- Resistance is the property of a material that limits current flow, measured in ohms.
- Direct current flows in one direction and is produced by batteries, static, and lightning.
- Alternating current periodically reverses direction and is produced by AC generators from power plants.
- AC current is used in homes and offices and can be reduced by power transformers.
- Computer components use direct current power produced by power supplies converted from alternating current.
- Voltage may also be referred to as potential difference or electromotive force.
