Electricity Terms Glossary Crossword Puzzle

QUESTIONS LIST:

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