    How much voltage does a standard automobile battery usually supply ?
    About 240 volts
    About 120 volts
    About 12 volts
    About 9 volts

    Which component has a positive and a negative side?
    A potentiometer
    A fuse
    A resistor
    A battery

    A cell, that can be repeatedly recharged by supplying it with electrical energy, is known as a:
    low leakage cell
    memory cell
    storage cell
    primary cell

    Which of the following is a source of EMF?
    germanium diode
    lead acid battery
    P channel FET
    carbon resistor

    An important difference between a conventional flashlight battery and a lead acid battery is that only the lead acid battery:
    has two terminals
    can be repeatedly recharged
    can be completely discharged
    contains an electrolyte

    A dry cell has a nominal voltage of 1.5 volt. When supplying a great deal of current, the voltage may drop to 1.2 volt. This is due to the cell's:
    electrolyte becoming dry
    internal resistance
    current capacity
    voltage capacity

    The most common primary cell in use today is the carbon-zinc or flashlight cell. This cell can be recharged:
    many times

    All storage batteries have discharge limits, and nickel-cadmium, the type most used in hand-held portables, should not be discharged to less than:
    0.5 volt per cell
    1.5 volt per cell
    0.2 volt per cell
    1.0 volt per cell

    To increase the current capacity of a cell, several cells should be connected in:
    parallel resonant
    series resonant

    To increase the voltage output, several cells are connected in:

    A nickel-cadmium battery should never be:
    left disconnected
    left overnight at room temperature
