|A roughly circular line, route, or movement that starts and finishes at the same place.
|A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
|the product of voltage and current
|A law stating that electric current is proportional to voltage and inversely proportional to resistance.
|a circuit having its parts connected serially.
|In physics and electrical engineering, a conductor is a material which contains movable electric charges. In metallic conductors such as copper or aluminum, the movable charged particles are electrons (see electrical conduction).
|An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
|An electromotive force or potential difference expressed in volts.
|electrical conduction through a gas in an applied electric field.
|Electromagnetism is the branch of science concerned with the forces that occur between electrically charged particles.
|The refusal to accept or comply with something; the attempt to prevent something by action or argument.
|a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
|a flow of electricity through a conductor; "the current was measured in amperes".
|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.
|is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge.
