Case 2: Current measurement
Figure 23 shows the current measurement circuit.
Figure 23.
Current measurement
Vin = (Iin + I) * Rsense = Iin * (1 + I/Iin) * Rsense
------------ (1)
I = (V1 - Vin)/R = V1/(R * (1 + Rsense/R))
------------ (2)
The following points should be kept in mind while using Rsense:
1.
Rsense should be chosen to correspond with the range of the current to be measured.
2.
Rsense affects the effective value of current I. To minimize its effect, it should be
negligible compared to R. Otherwise ADC has to be compensated.
