Series Low Current Measurements

Basic Current Measurements tions, errors induced by the voltage burden (or drop) across the
entire ammeter model, and the uncertainty of the meter itself.
In a typical circuit (see Figure 1a), a source causes a current (I)
to flow through the circuit. The goal of any electrical current With measurements of currents in the normal range (typically
measurement is to insert an amme
