I am trying to calculate the minimum insulation resistance of two parts (a capacitor and box) that are approximately 0.38mm apart or 0.00038m.
I've tried looking at resistivity of air which some people are giving as 1.3 × 10^16 per meter.
Would the equation 1.3x10^16 x 0.00038 = insulation resistance be accurate?
I am guessing no as I imagine the voltage applied and cross sectional area would also have an impact. I need the insulation resistance to be at least 50MOhms @ 50VDC.
Could you please advise.
Thank you in advance.
