An equation which describes v 0 as a function of v i and position x of the movable contact of the voltage divider is to be derived for the figure shown below. Concept introduction: An inverting amplifier circuit is shown here. Variable resistance is used when one part from 0 to position of the contact x, appears in the feedback loop and the remaining portion appears at the input. Since the op-amp has very high input resistance, input current will be entirely flowing through the feedback loop. Using this, we can find the output voltage in terms of the position x and input voltage v i .

The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage. The values of the parameters depend on the voltage and temperature; suppose ? = 2.2 and ? = 220. (a) What is the probability that a specimen's lifetime is at most 250? Less than 250? More than 300?
