  1. The frequency limits of the “20 metre band” are:
    1. 14.00 to 14.10 MHz
    2. 14.00 to 14.45 MHz
    3. 14.00 to 14.50 MHz
    4. 14.00 to 14.35 MHz

  2. The following band is allocated to New Zealand amateur radio operators on a primary basis:
    1. 3.5 to 3.9 MHz
    2. 10.1 to 10.15 MHz
    3. 146 to 148 MHz
    4. 21 to 21.45 MHz

  3. An atom that loses an electron becomes:
    1. a positive ion
    2. an isotope
    3. a negative ion
    4. a radioactive atom

  4. In an n-type semiconductor, the current carriers are:
    1. holes
    2. electrons
    3. positive ions
    4. photons

  5. The unit for potential difference between two points in a circuit is the:
    1. ampere
    2. volt
    3. ohm
    4. coulomb

  6. A current of 5 ampere in a 50 ohm resistance produces a potential difference of:
    1. 20 volt
    2. 45 volt
    3. 55 volt
    4. 250 volt

  7. When an 8 ohm resistor is connected across a 12 volt supply the current flow is:
    1. 12 / 8 amps
    2. 8 / 12 amps
    3. 12 - 8 amps
    4. 12 + 8 amps
