It is easier to diagnose electrolyzer electrical issues using voltage. \u00a0Ohm-meters are unreliable when testing electrolyzers.If there is a direct short somewhere, (preventing normal application of power without blowing a fuse), then use my simple and inexpensive capacitive amperage limiting technique to control the amperage and prevent the short from being an issue; then test electrolyzer conditions with a voltmeter.
\nOhm-meters are unreliable when testing electrolyzers for many reasons, some conflicting with each other, some exacerbating. Examples include:
\n1. Ohm-meters actually send a current through the \u2018load\u2019 to measure the load resistance. \u00a0ANY current will activate the electrolyzer, making gas and affecting the actual resistance. \u00a0High impedance ohm-meters minimize this issue because they use less current but will still show a varying resistance as conditions in the electrolyzer change.
\n2. Some conditions in the electrolyzer that affect resistance are: electrolyte type, electrolyte density, electrolyte temperature, electrode shape, electrode material, buildup of non-conductive or dielectric material on the electrodes (usually by electrodeposition on the negative or oxidation on the positive), impurities in the electrolyte, etc.
\n3. Electrolyzers can become \u2018polarized\u2019 and thus give a different resistance reading if you switch the ohm-meter probes one way or the other.
\n4. Electrolyzers often act like capacitors and\/or \u2018store\u2019 a charge in a variety of ways (in the electrolyte and on the electrodes). \u00a0This charge usually dissipates over time but ohm-meters are not configured to compensate for it. \u00a0The charge will \u2018skew\u2019 the meter\u2019s reading, creating more or less \u2018resistance\u2019 reading, depending on the polarity tested.
\nSo my advice would be to NOT use an ohm-meter to diagnose any issues with an electrolyzer, except very general ones, and certainly don\u2019t trust that the meter reading to accurately tell you much about what is going on inside the electrolyzer; there are too many variables.
\nIf you do use an ohm-meter, at least be aware of the variables, and how each one affects the resistance reading, so that you can use the readings to generally diagnose some issue.
\nSince there are so many ways for the resistance to vary in an electrolyzer, and the resistance varies continually as conditions change, there is never a \u2018fixed\u2019 resistance or even a \u2018stable\u2019 resistance in an electrolyzer. \u00a0The only way you can accurately determine a \u2018resistance\u2019 (at any given time) is to use the Ohms Law formula as expressed, R = E\/IR = ResistanceI = AmperageE = Voltage
\nThe varying resistance of electrolyzers is not that big of a deal, no magic or anything \u2018over unity\u2019 interesting. \u00a0It\u2019s just a side effect of electrolyzer conditions at any given time. \u00a0This is normal, natural and easily understood.
\nNow the way electricity interacts with the electrolyte and the cell design parameters\u2026 That\u2019s interesting! \u00a0And exploring that has (so far) led me to electrolyzer efficiencies less than 1 watthour per STP liter of BG produced.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product-resource-group":[107],"restricted-resource-tag":[],"class_list":["post-992","product-resource","type-product-resource","status-publish","hentry","product-resource-group-hyzor-resources"],"acf":[],"_links":{"self":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource\/992","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource"}],"about":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/types\/product-resource"}],"wp:attachment":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/media?parent=992"}],"wp:term":[{"taxonomy":"product-resource-group","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource-group?post=992"},{"taxonomy":"restricted-resource-tag","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/restricted-resource-tag?post=992"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
