WebWe can see from the above examples that a capacitor when connected to a variable frequency supply, acts a bit like a frequency controlled variable resistance as its reactance (X) is “inversely proportional to frequency”. At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect … WebI am assuming we are talking about relatively small capacitors and voltages here. If you start talking about high voltages that could be fatal then what you want a professionally manufactured device and extra precautions. Here is an article where someone made a nice discharge probe from a Bic pen. He also goes into the math if you are curious.
