I am building a device that measures current in various ranges. For this I want to switch in different current sense resistors. To do this I see two ways: the resistors in series or the resistors in parallel.
They produce slightly different values, but that doesn't really matter all that much, because I have to calibrate it for the actual values anyways.
But I am wondering if there are any inherent advantages or disadvantages of one method over the other for current sense purposes.
