electric current | the rate at which charges pass through a given point; measured in amperes |
potential difference | the difference in potential energy between two location |
voltage | the potential difference between two points; measured in volts |
insultor | 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 |
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 |
switch | a device used to control the flow 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 |
