ammeter - A device for measuring electric current in a circuit., amps - Units of measurement of electric current, symbol A., atoms - A tiny particle containing protons and neutrons in a nucleus, and electrons. , attract - Be pulled together, for example, opposite poles of a magnet attract and positive and negative charges attract., battery - Two or more electrical cells joined together., cell - A chemical store of energy, which provides the push that moves charges around a circuit., charged up - When materials are rubbed together, electrons move from one surface to the other., current - Flow of electric charge, usually electrons, in amperes (A)., electrical conductor - A material that allows current to flow through it easily, and has a low resistance., electrical insulator - A material that does not allow current to flow easily, and has a high resistance., electric charge - A property of a material, the electric charge can be positive, negative, or neutral., electric field - A region where a charged material or particle experiences a force., electron - Tiny particles that are part of atoms and carry a negative charge., electrostatic force - Non-contact force between two charged objects., lightning  - Occurs when electrons jump from one charged area to another and produce a big current., negatively charged - An object that has gained electrons as a result of the charging process., neutral - Describes an object or particle that has no charge, or in which positive and negative charges cancel out, giving no overall charge., ohms - The units of resistance, symbol Ω., parallel - If some components are in separate loops in an electric circuit., positively charged - An object that has lost electrons as a result of the charging process., potential difference - The potential amount of energy shifted from the battery to the moving charge, or from the charge to circuit components, in volts (V)., rating - The value of potential difference at which a cell or bulb operates., repel - Be pushed away from each other, for example, like magnetic poles repel or like electric charges repel., resistance - A property of a component, making it difficult for charge to pass through, in ohms (Ω)., series - If components in a circuit are in the same loop in an electric circuit., voltage - The amount of energy shifted from the battery to the moving charge, or from the charge to circuit components, in volts (V)., voltmeter - A device for measuring potential difference (voltage)., volts - Unit of measurement of potential difference (voltage), symbol V.,
