Term | Definition |
---|---|
Ammeter | A low-resistance device wired in series in an electric circuit , used to measure the current. |
Circuit | The complete path of an electric current including the source of the current and the resistors. |
Direct Current (DC) | An electric current that flows in only one direction |
Electric Current | The flow of electric charge, measured as the rate at which electric charge flows past a given point. |
Electric Circuit | A closed path in which an electric current can flow. The path must include a source of potential difference, and may include one or more resistors. |
Equivalent Resistance | A single resistance that is equivalent to a set of resistances in a series or parallel circuit. |
Grounding | The addition or removal of electrons to or from an object in order to neutralize its charge. |
Kirchhoff's Law | Conservation of charge: The sum entering any current junction is equal to the sum leaving that junction. |
Parallel Circuit | A circuit in which there is more than one current path. |
Series Circuit | A circuit in which there is only one current path. |
Voltmeter | A high-resistance device used to measure the potential difference across two points in an electric circuit. |
