Lowering Ammeter Input Impedance
Abstract
Feedback circuit operates in conjunction with sensitive microammeter or other current-measuring instrument to reduce input impedance of composite circuit. In contrast with older current-amplifier circuits, current much less subject to drift and noise, calibration not necessary, and values of components not critical.
