Sensitivity values has been calculated for the upper and lower band of a voltmeter at 20V and 150V and the values are obtained as follows. If the calibration curve looks

like the y =ax' curve, estimate the following: Find the value of a and b (10 points) The sensitivity of sensor at X = 15 V (5 points) The sensitivity of sensor at X=60 V (5 points) Explain in your own words the static sensitivity (5 points)
