AMMETERThe deflection of the pointer in the D'Arsonval meter movement isproportional to the meter current I. Therefore, this instrument can be used to measure current.However, the meter movement by itself is of limited use and capability, since its full-scale current value IFS is practically too small (at most in the order of milliamperes). If the current allowed to flow in the movement, Im, exceeds IFS, permanent damage can result, in particularto the restraining springs.To be able to measure currents higher in value than IFS of a given meter movement, the division principle is applied.
