# Electricity

circuit a roughly circular line, route, or movement that starts and finishes at the same place
conductor a person who directs the performance of an orchestra or choir
electric current Electric current is a flow of electric charge through a conductive medium
electric discharge Electric discharge describes any flow of electric charge through a gas, liquid or solid
electric field An electric field is the region of space surrounding electrically charged particles and time-varying magnetic fields.
electric force To understand electric fields and electromagnetic waves, you need to know how charges (such as "negative" electrons and "positive" protons ) cause each other to move.
electric power Electric power is the rate at which electric energy is transferred by an electric circuit
insulator An electrical insulator is a material whose internal electric charges do not flow freely, and which therefore does not conduct an electric current, under the influence of an electric field
ion An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
ohm's law Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.
parallel circuit one connected completely in parallel is known as a parallel circuit.
resistance a measure of the degree to which an object opposes an electric current through it
series circuit A circuit composed solely of components connected in series is known as a series circuit
static charge tatic electricity is an excess of electric charge trapped on the surface of an object
voltage is the electric potential difference between two points — or the difference in electric potential energy of a unit test charge transported between two points
