Static/dynamic Resistance Measuring Apparatus and Method

摘要

A resistance measuring apparatus which includes a variable voltage source, a signal display circuit, a bridge consisting of a first standard resistor, a second standard resistor, an adjustable resistor and the unknown resistor, a bridge balance display circuit and a dynamic voltage display circuit alternatively connected within the bridge. The resistance measuring apparatus is adapted to measure static resistance and dynamic resistance variation of an unknown resistor in the case of external environment having changed dramatically.
