The flow of electric charge.
A material that allows for the transfer of thermal energy, or electric current.
A material that will not conduct heat or electricity, or does so very poorly.
A material that allows for partial conductivity. It conducts better than an insulator, but not as well as a conductor.
A closed, circular conducting path, that allows current to return to its origin.
A device placed in a circuit that can be used to open, or close the circuit.
When there is a connection, usually unintentional, that allows electric current to bypass part of the circuit, and follow the path of least resistance.
The SI unit that measures the difference in electric potential.
Unit of measure used to express electrical charge.
A unit of measure used to express current, the amount of electric charge that passes a point in one second.
An object that impedes, or slows down the flow of electrons.
Current is directly proportional to voltage, and inversely proportional to resistance. Rearranged, voltage equals current multiplied by resistance.
The SI unit of resistance.
A resistive device in an electrical circuit.
An electrical circuit arranged in a simple loop, so that electrons have a single path to follow.
An electrical circuit that has multiple branches for electrons to follow.
A device used in a circuit that melts when excess current passes through it, breaking the circuit.
A device that interrupts, or breaks, a circuit when the current exceeds a given value.
The standard SI unit for power, defined as 1 joule per second.
1000 watts, used to measure larger amounts of power.
