WebMay 3, 2016 · Internal Resistance When designing a circuit with a battery, we often assume that the battery is an ideal voltage source. This means that no matter how much or little load we attach to the battery, the voltage at the source's terminals will always stay the same. WebSep 17, 2015 · According to the graph as voltage decreases, current increases. The only way I can explain it using the equation V=e-rI is that for some reason internal resistance r increases and as eloctromotive force stays the same, this means decrease in voltage V so both sides equal each other again.

A suitable op-amp follower might have a drift of +/-50~+/-500mV/minute with a 15pF cap on the input and an input of a volt or so. One problem is that the op-amp itself might have 5pF of input capacitance so you'd change the voltage by connecting it to the capacitor. song fishing in heaven
