Oct 11, 2023 at 3:07 | comment | added | Dave Tweed | The point is, at high frequencies and high resistances, even tiny parasitic capacitances become very significant. For example, at 50 kHz, just 3 pF of stray capacitance has an impedance of 1 megohm, which is low enough to affect your measurements. | |
