hi every one - rather a strange question for you all - which i would appreciate any thoughts on - it may seem a tad odd - but please bear with me .
i have a phenomia going on here that is puzzling me - that of capacitors - charging and discharging themselves - and in some cases giving negative voltage readings - i have at the moment two capacitors being used for the ongoing experiment - both of which are new - have never had a voltage applied to them ( so this will hopefully rule out capacitor soak ) - the first is a one farad /24v and the second is a 10,ooo uf /40v - the 1 farad one is connected directly to a dipole antenna of circular configuration - eg a loop insulated in the middle - with an arm of the dipole connected to each terminal - the second is a stand alone capacitor - in a plastic casing with nothing connected to the terminals - the voltage on the capacitors is monitored daily - and before any test runs are commenced each is shorted AND grounded to a proper earth ground - for some considerable time ( hours ) - but as soon as they are brought into the house they start to pick up charge - running into many hundreds of Milli volts (dc )
today i measured the larger of the two and it had swung from a positive to a negative voltage of 45.7mv the previous reading 5 days ago ( have been busy else where ) being + 43.3 mv !
OK - now i have been told by so called experts that this phenomena is impossible - however it is happening - other wise i would not be wasting my time or yours asking this question
as to WHY i am doing these tests ?? - sorry guys if i told you that it would detract from the discussion
any assistance or thoughts would be welcome on this puzzling matter
best regards
Brett
