I have read that between breadboard nodes there can be as much as 25 pF of capacitance. I have a much better time understanding how parasitic induced voltages work, with respect to magnetic fields. I have a much harder time understanding how signals can become noisy due to parasitic capacitance. I don't understand time varying electric fields as well as magnetic fields. Can some one help me understand how capacitance between nodes, can manifest itself as a noisy signal in said circuits?
