    B-005-03-01
    What is the word used to describe how fast electrical energy is used?
    Current
    Power
    Voltage
    Resistance

    B-005-03-02
    If you have light bulbs marked 40 watts, 60 watts and 100 watts, which one will use electrical energy the fastest?
    They will all be the same
    The 40 watt bulb
    The 100 watt bulb
    The 60 watt bulb

    B-005-03-03
    What is the basic unit of electrical power?
    The ampere
    The volt
    The watt
    The ohm

    B-005-03-04
    Which electrical circuit will have no current?
    A short circuit
    An open circuit
    A complete circuit
    A closed circuit

    B-005-03-05
    Which electrical circuit uses too much current?
    A dead circuit
    A short circuit
    A closed circuit
    An open circuit

    B-005-03-06
    Power is expressed in:
    volts
    amperes
    watts
    ohms

    B-005-03-07
    Which of the following two quantities should be multiplied together to find power?
    Inductance and capacitance
    Voltage and inductance
    Voltage and current
    Resistance and capacitance

    B-005-03-08
    Which two electrical units multiplied together give the unit "watts"?
    Volts and farads
    Farads and henrys
    Amperes and henrys
    Volts and amperes

    B-005-03-09
    A resistor in a circuit becomes very hot and starts to burn. This is because the resistor is dissipating too much:
    voltage
    resistance
    current
    power

    B-005-03-10
    High power resistors are usually large with heavy leads. The size aids the operation of the resistor by:
    allowing higher voltage to be handled
    increasing the effective resistance of the resistor
    allowing heat to dissipate more readily
    making it shock proof

    B-005-03-11
    The resistor that could dissipate the most heat would be marked:
    100 ohms
    2 ohms
    20 watts
    0.5 watt
