Study Notes
Electrical Circuits
- An electrical circuit is a path through which electric current flows from a power source, through one or more devices, and back to the power source.
Circuit Diagrams
- The symbol for a cell in a circuit diagram is ℰ.
Electric Current
- The measure of the flow of electrons around a circuit is electric current, typically measured in amperes (A).
- Electric current flows from the positive terminal of the power source, through the circuit, and back to the negative terminal of the power source.
