    Angular parallel plates capacitor

    Hi, I hope you good people can enlighten me on this, Parallel plates capacitor charge and/or capacitance calculations are well known, suppose one take a rectangular shaped capacitor and bend it 90 degrees into an "L" shaped capacitor. What effect that will have on capacitance and/or charge of...

    Please help with info about a HOT-WIRE Supply kit

    Thanks for your quick reply - Minder, well, unfortunately, I don't know the original owner who has now passed away, from the paraphernalia - he was well into electronics and esp power, but why he had a hot-wire kit - I will never know.

    Please help with info about a HOT-WIRE Supply kit

    Hi All, Great forum thanks to all that made it possible, I helped with a house clearance after the owner passed away, Along with fair bit of electronics components such as resistors, caps etc I came across a piece of equipment called " HOT-WIRE SUPPLY BY KEYBURN SYSTEMS", Google search...

    Please Please Help Me Understand This ...

    Hi All, Great forum, thank you to all who made it possible, I conducted a simple experiment but I not able to understand/explain the results, In large bowl full of material composed mostly of: FINE SAND + WATER + SALT(natural unrefined) probably in equal parts which made it look like a paste...

    Salty ground voltage

    thanks for the explanation ... If I am to protect the electrodes by covering then with a thin layer plastic film will that stop the galvanic reaction? another of putting it ... can I have a galvanic cell reaction with corrosion?

    Salty ground voltage

    Thanks for your reply - M, can the said corrosion be reversed by applying a voltage to the cell?

    Salty ground voltage

    Hi all, I hope - you clever people can enlighten me on strange phenomenon I observed today ... In a small patch of salty wet ground I stuck two rods, copper and Aluminium, no matter the distance the voltage reading was always 0.6V, the copper side being the +. Can someone please explain what...

    Cooling Fan blowing the fuse

    Thanks for your input guys, Indeed I do have a MMeter with AC-DC clamp, by connecting the fan straight to the battery the current draw was about 10amps! still not sure it is blowing the 30Amps fuse, I am going to change one of the wires that appear to be bit too thin, that might help.

    Cooling Fan blowing the fuse

    Clutch fan (viscous ) is a thermostatic device that due to temp changes can activate a "clutch" for the engine to drive the fan faster, it is fitted as standard on most large older engines such as trucks etc ... (there you go I hope you learnt something new?)

    Cooling Fan blowing the fuse

    Thanks for your reply - Minder, No I did not, I suppose I could hook the fan straight to battery, to measure current, I could use clamp on multimeter? right?

    Cooling Fan blowing the fuse

    Hi All, I hope you clever people can help me with my problem, On my car I changed the clutch fan with an electric one, the fan is wired through a 40Amps Relay, everything works ok for a while then the fuse just melts away! I used fuses as high as 30Amps! The fan motor is ok, the relay has...

    Corrosion resistant electrodes

    Thanks Alec, I think a layer of lacquer might be too fragile for my setup, some metal rods/tubes will do the trick ... but which metal(s) is the question?

    Corrosion resistant electrodes

    Hi All, I hope you can help me with my quest, I need advice about corrosion-resistant materials to use as electrodes for a form of a capacitor that uses saline brine electrolyte - am not able to change the electrolyte so that is why I need to source the electrodes that will cope with the...

    supercapcacitor based battery

    Thanks guys, I just think it is about time to look into cap based energy storage with all these wonderful new materials being discovered such as graphene etc ... I am aware of the limitations of traditional caps but I am hoping that some well read clever people on this forum can come up with...

    supercapcacitor based battery

    Hi all; Please excuse me if my question appear basic; If I am to make a super dupper large capacitor that is able to hold a lot of charge (using graphene for example); 1) is there any way I can prevent it from self discharging; I dont mind a small amount of self disharging 2) how can I use the...

    Turning supercapacitors into batteries

    Thanks - Dorke for your prompt reply, to be honest - I am thinking aloud at the mo, I have been reading about making SC using activated charcoal in an aqueous solution, apparently these can be pretty powerful ... me thinking why can't these be turned into batteries, then I read about the fast...

    Turning supercapacitors into batteries

    Hi All, I have been pondering this for a while ... If once can make or buy a very beefy supercap say few 100farads, 1. can one treat a supercap with that much storage cap as a battery? 2. if so what circuit can be used to allow the SC to be used as a battery for prolonged discharge thanks for...
