Term | Definition |
---|---|
Electric Current | the rate at which charges pass through a given point; measured in amperes. |
Potential Difference | the difference in potential energy between two locations |
Voltage | the potential difference between two points; measured in volts . |
Insulator | a material that does not conduct heat of electrical energy well; often used to prevent energy from leaving a particular area . |
Circuit | a closed path through which electricity can flow . |
Load | a device in a circuit that does work using electrical energy . |
Conductor | a material that allows heat or electrical energy to flow through it easily . |
Resistor | an object added to a circuit that restricts the flow of electrical energy ; inhibits the flow of electric current by producing a voltage drop when current passes through it. |
Switch | a device used to control the flow of current through a circuit . |
Series Circuit | a circuit in which the parts are joined one after another such that the current in each part is the same . |
Parallel Circuit | a circuit in which the parts are joined in branches such that the potential difference across each part is the same. |
