a closed conducting circle or loop through which current can flow

a substance or object that allows electricity to flow through it with low resistance

the flow of electrons through a conductor

an iron or steel core that is magnetized by electric current in a coil that surrounds it

a substance or object that does not conduct electricity

unit of electrical resistance

an electrical circuit in which electric current has multiple paths through which it can flow

measure of how much a material opposes the flow of electric current; measured in ohms

a material or object that is designed offer a desired amount of resistance to the flow of electrical current

a diagram of an electrical circuit

an electrical circuit in which electric current has only one path through which it can flow

unit of measure for the difference of potential that would drive one ampere of current against one ohm resistance

potential difference between positively-charged and negatively charged terminals of a battery, or between any two given points in a circuit; measured in volts; V=IR
