Problem: Error in Low Voltage, Low Current Measurements
... Potential Cause: Voltage Burden One of the biggest sources of error in measuring low currents from low voltage sources is voltage burden. Unlike an ideal ammeter, a shunt style ammeter (for example, in a DMM) has some resistance, and current flowing through it will create a voltage drop. This voltage ...

... provides the charge. Although there is less charge provided by V1, the ratio of Voltage/Resistance for V1/R1 is larger than V2/R2. So despite the fact that more charge is flowing from V2, R2 is reducing the charge much more. So I1>I2. [Careful not to confuse charge flow with voltage. Voltage is just ...
