Study Notes
Circuits and Circuit Diagrams
- A circuit is a closed loop allowing energy flow, containing a power source, wires, one or more loads, and a switch.
- Circuit diagrams use symbols to represent components within a circuit. These are standardized for clarity.
- Common circuit diagram symbols: wire, switch (open and closed), ammeter, voltmeter, light bulb, battery (single cell and multiple cells). The longer line in a battery symbol represents the positive electrode, while the shorter line represents the negative.
- Circuit diagrams depict the arrangement of electronic components.
Series Circuits
- A series circuit has loads connected end-to-end.
- Electrons flow through only one path.
- The current is the same through each load.
Parallel Circuits
- In a parallel circuit, loads are connected by branches.
- Electrons can flow through multiple paths.
- The voltage across each load is the same.
- Household electrical outlets are wired in parallel.
Circuit Symbols
- Symbols represent components in diagrams.
- Examples include conducting wires, cells, batteries (multiple cells), lamps, resistors, ammeters, voltmeters, and switches.
