A Wheatstone bridge has a 24 V supply, all four resistors equal 5 kΩ and a galvanometer with a 15 Ω resistance and a sensitivity of 1.5 μA/mm. Compute the minimum detectable change in measured resistance. Compute the accuracy of measurement of Wheatstone bridge if it employs precision resistors with 0.05% accuracy and an adjustable precision decade resistance box with an accuracy of 0.02%.
