    Answer and Explanation:

    An analog instrument is one which provides the output which varies with time on a continuous basis or we can say that the output obtained from such instrument is a continuous function of time. This includes the instruments like ammeter, voltmeter, etc.

    Significant figures in a measurement determines the degree of precision of a measurement or how the readings recorded are close to each other or how precise the measurement is.

    Thus in order to determine the number of significant figures in a measurement recorded the figure of least significance is evaluated by reading in between the instrument's smallest markings.
