  1. 4. a material through which electric current can pass. In general, metals are good conductors. Copper or aluminum is normally used to conduct electricity in commercial and household systems. (Compare insulator.)
  2. 10. the negative charge of a atom
  3. 11. a schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.
  4. 13. current (AC):an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
  5. 14. an electric current is a flow of electric charge
  6. 15. the ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.

  1. 1. in electrical engineering, a switch is an electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another.
  2. 2. is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground (earth) for several reasons.
  3. 3. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
  4. 5. resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased.
  5. 6. circuit:A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load.
  6. 7. current (DC): Current Flowing in power lines and normal household electricity that comes from a wall outlet is alternating current.
  7. 8. circuit:A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage, and the total circuit current is equal to the sum of the individual branch currents.
  8. 9. an electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conducts electric current more easily.
  9. 12. an electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conducts electric current more easily.
