Questions and Answers
  • 1. 
    How does a circuit work?
    • A. 

      Electrons circle around the circuit, speeding up each time, as long as the circuit is open.

    • B. 

      Electrons circle around the circuit, speeding up each time, as long as the circuit is closed.

    • C. 

      Electrons circle around the circuit, slowing down each time, as long as the circuit is closed.

    • D. 

      Electrons go up and down, creating electrical power.

  • 2. 
    The job of a resistor is to act as a roadblock and lower the level of voltage. This stops the circuit from burning up.
    • A. 

      True

    • B. 

      False

  • 3. 
    Is it true an IC chip, a transistor and a relay are all types of resistors?
    • A. 

      True

    • B. 

      False

  • 4. 
    What do the four coloured stripes on a resistor stand for (in order)?
    • A. 

      Digit 1, Digit 2, the level of tolerance, and the multiplier

    • B. 

      Digit 1, Digit 2, Digit 3, and the multiplier

    • C. 

      Digit 1, Digit 2, Digit 3, and the level of tolerance

    • D. 

      Digit 1, Digit 2, the multiplier, and the level of tolerance

  • 5. 
    What is the p-n junction?
    • A. 

      A boundary between two semi-conductive materials in the same shell. This is used to light an LED (Light Emitting Diode)

    • B. 

      A junction where two pieces of wire meet

    • C. 

      The terminal clips (connecting pieces)

    • D. 

      A junction between two metals which let voltage flow through them

  • 6. 
    A resistor is made from carbon or other semi-conductive materials.
    • A. 

      True

    • B. 

      False

  • 7. 
    The three prongs on a transistor are called the base, the collector and the emitter. A transistor is "polarised", meaning that it can only be fitted one way round
    • A. 

      True

    • B. 

      False

  • 8. 
    The resistance of a resistor is measured in ohms Ω
    • A. 

      True

    • B. 

      False
