Vernier Caliper Least Count & Length Reading Formula
Vernier caliper least count formula, since vernier calipers can efficiently measure dimensions up to 10 -3 cm, they are extensively used veernier measure the internal and external diameters of tubes as well as the dimensions of many more objects. When measuring the length of a line, the zero of the vernier scale lies between To get the best deal on Tutoring, call Toll Free.
