Buying a more accurate instrument to measure resistance and impedance won’t always improve the accuracy of your measurements. Your problems could be caused by measurement errors that originate in your ...

The input capacitance of an op amp often lies in the picofarad range, making it difficult to measure because parasitic effects in the test setup distort the result. But, with a small test setup ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...
