  • GCSE Design & Technology
    Materials & Components
    A Qwizdom Presentation
  • What does an electrical conductor do?
    An electrical conductor allows electricity to flow through it easily.
    An electrical conductor prevents electricity from flowing.
    An electrical conductor is a type of plastic material.
    All of the above
  •  What is a material that can exhibit both
    insulating and conducting properties?
    Conductor
    Insulator
    Semi-conductor
    Demi-conductor
  • An insulator has what sort of value?
    A high resistivity value
    A high conductance value
    A high material value
    All of the above
  •  When light falls on an LDR, its resistance
    will:
    Increase
    Double
    Stay the same
    Decrease
    Halve
  • A thermistor is a component that changes its
    resistance in response to a change in:
    Light
    Temperature
    Pressure
    Current
    Moisture
  • Two transistors can be joined together to form
    a:
    Darlington pair
    Durham pair
    Doncaster pair
    Dundee pair
  • A miniature circuit that is etched onto a piece of
    silicon is called
    A transistor
    A semiconductor
    A discreet component
    A dual-in-line package
    An integrated circuit
  • What is the unit of resistance?
    Ohms
    Volt
    Farad
  • What is the resistance of a resistor designated as
    3k3?
    33 kilo-ohms
    0.33 kilo-ohms
    3.3 kilo-ohms
  • In a resistor colour-code, what resistance value
    is indicated by brown, black, orange?
    100000 ohms
    1000 ohms
    10000 ohms
  • An electrolytic capacitor can be connected
    either way round in a circuit:
    True
    False
  • Which of the following is NOT a lead connected to a transistor
    Base
    Emitter
    Follower
    Collector
  • Capacitors are components that store electrical
    charge. Capacitance is measured in:
    Farads
    Ohms
    Joules
  • What is a potential divider?
    A potential divider is made up of two capacitors in parallel.
    A potential divider is made up of two capacitors in series.
    A potential divider is made up of a resistor and capacitor
    A potential divider is made up of two resistors in parallel.
    A potential divider is made up of two resistors in series.
  • Diodes are often used for changing alternating
    current into direct current - a process known as
    rectification.
    True
    False
