Study Notes
Electric Current
- Electric current refers to the flow of electric charge.
- The unit used to measure electric current is the ampere (A).
- Electric current can only flow in a closed circuit, meaning a path that allows the current to return to its source.
- Electric current is measured in amperes (A), not volts (V), which are used to measure electric potential difference.
Electric Resistance
- Resistance is a property that opposes the flow of electric current in a material.
