Physical World and Measurement

A galvanometer is an electrical flow estimation instrument that is electromechanical. A galvanometer answers an electrical flow going through a curl during a proceeding with the attractive transition by diverting a pointer. Galvanometers are considered to be a kind of actuator. The Moving Coil Galvanometer The galvanometer is an instrument used to determine an electrical […]

The origin of callipers goes back to the ninth A.D Qin dynasty. The second addition to reduce the error rate was that of a vernier calliper made in 1631 by the French mathematician Pierre Vernier.  The main use of vernier callipers is to measure internal and external dimensions or distances with extreme precision. Vernier callipers

Vernier Calipers Vernier calipers are measuring instruments that are used to calculate precise linear measures. It calculates the straight linear distance between two points in layman’s terms. It could be as simple as a compass with inside and outside points. The tips of the calliper are first fixed to fit across the spots to be

The accuracy of a measurement refers to how near it is to the proper value for that measurement. The precision of a measurement system refers to the degree to which repeated measurements coincide (Which are repeated under the same conditions). Measurements can be both exact and accurate, precise but not accurate, precise but not accurate,
