Study Notes
Basics of Electricity
- Electricity is a form of energy resulting from charged particles, existing as either a static charge or a dynamic current.
Electric Circuit
- An electric circuit requires a source of energy, such as a cell or battery.
- A circuit is a complete pathway for electricity and must be closed for a device to work, such as a light bulb.
- A circuit can be defined as a closed system that transfers electrical energy.
Basic Components
- Power Source (Voltage): Provides the energy to push electricity through the circuit.
- Connectors: Join all parts together to create a path for electricity to flow through.
- Load: The device being powered by the electricity in the circuit, such as a light bulb.
- Control: Switches the power on or off, creating either a closed or open circuit.
