P1.3 Keywords

P122
  1. Charge (2) - P1:2
    • The physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges; positive and negative.
  2. Resistance (2) - P1:2
    • the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation.
  3. Circuit (1) - P1:1
    • A complete and closed path around which a circulating electric current can flow.
  4. Electric field (1) - P1:1
    • A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
  5. Electrons (1) - P1:1
    • A stable subatomic particle with a negative charge.
  6. Transformer (1) - P1:1
    • An apparatus for reducing or increasing the voltage of an alternating current.
  7. Alternating current (1) - P1:1
    • An electric current that reverses its direction many times a second at regular intervals
  8. Parallel (1) - P1:1
    • Components connected in parallel are connected along multiple paths.
  9. Series (1) - P1:1
    • Components connected in series are connected along a single path.
  10. Work (1) - P1:1
    • Defined as the product of a force and the distance over which the force is applied. Measured in joules.
  11. Domestic (1) - P1:1
    • For use in the home rather than in an industrial or office environment.
  12. Static (1) - P1:1
    • Having no motion.
  13. Charge flow (1) - P1:1
    • The amount of electricity travelling through a circuit
  14. Power (1) - P1:1
    • The amount of energy transferred per unit of time. (Expressed in Watts)
  15. National Grid (1) - P1:1
    • The network of high-voltage power lines that connect major power stations to consumers.
  16. Current (1) - P1:1
    • The ordered directional movement of electrically charged particles.
  17. Transfer (1) - P1:1
    • To convey or cause to pass from one place, person, or thing to another.
  18. Appliance (1) - P1:1
    • a device or piece of equipment designed to perform a specific task.
  19. Direct current (1) - P1:1
    • an electric current flowing in one direction only.
  20. Transmit (1) - P1:1
    • cause (something) to pass on from one person or place to another.
  21. Ohms (1) - P1:1
    • the SI unit of electrical resistance, transmitting a current of one ampere when subjected to a potential difference of one volt.
  22. Mains electricity (1) - P1:1
    • the form of electrical power that is delivered to homes and businesses.
