The output of an LVDT is connected to a 5 V voltmeter through an amplifier whose amplification factor is 250. An output of 2 mV appears across the terminals of LVDT when the core moves through a distance of 0.5 mm. The milli-voltmeter scale has 100 divisions. The scale can be read to 1/5th of a division. Calculate the resolution of the instrument (in μm).
