I understand protoboards have several limitations for prototyping circuits. However, most information found deals with parasitic capacitance such as to cause problems with higher frequency circuits.
My question is what are the limitations of breadboards in regards to high impedance circuits? I'm attempting to measure the voltage drop across a basic voltage divider circuit. Vout is across a fixed 10 Mohm resistor while the other resistance is a variable resistor of a sensor (500 kohm to ~1 Gohm).
