saturnx21 Posted April 16, 2008 Share Posted April 16, 2008 I have just posted in another thread on this forum, and what I put was: lowest stable ohmage My question is simple is "ohmage" a real word? If not I wonder the best way of phasing it instead? :) Link to comment Share on other sites More sharing options...
bruce Posted April 16, 2008 Share Posted April 16, 2008 Impedance is probably closer. But a clearer way of expressing it would be "lowest impedance for stable operation" or something like that. Link to comment Share on other sites More sharing options...

J Pearce Posted April 16, 2008 Share Posted April 16, 2008 Resistance doesn't take frequency into account like impedance? Link to comment Share on other sites More sharing options...
Ynot Posted April 16, 2008 Share Posted April 16, 2008 In the strictest of terms, no - it is not a 'proper' word.But it is something that in some circles is a bit of a colloquialism.Something akin to Ampage. It basically stems, I'd say, from the fact that we say Voltage (correctly), so over the decades it has fallen occasionally into use. EDIT - fixed my fat-finger slip!! :) Link to comment Share on other sites More sharing options...
mackerr Posted April 17, 2008 Share Posted April 17, 2008 What's wrong with resistance?Impedance is the combination of resistance, inductance, and capacitance. In speakers most of the impedance is due to resistance, but there is also significant inductance. Speakers have a "nominal" impedance, usually 4, 8, or 16 ohms, but the actual impedance is a complex curve related to frequency. Mac Link to comment Share on other sites More sharing options...
Rob_Beech Posted April 17, 2008 Share Posted April 17, 2008 Resistance is measured on a passive/dead circuit. .....I think.... it's late... Link to comment Share on other sites More sharing options...
Wuddy Posted April 17, 2008 Share Posted April 17, 2008 Resistance measured in Ohms is the property of a conductor to limit the flow of current through it when a voltage is applied. When the supply voltage is alternating, a second effect, know as reactance has to be considered. It applies only when the circuit includes inductance and/or capacitance, and its value, measured in Ohms, depends on the frequency of the supply as well as on the values of the inductance and/or capacitance concerned Impedance is the effect which limits alternating current in a circuit containing reactance as well as resistance Link to comment Share on other sites More sharing options...

Chappie Posted April 17, 2008 Share Posted April 17, 2008 It's not in my Oxford English dictionary though. I think it may be American English. Link to comment Share on other sites More sharing options...
grizzly Posted April 17, 2008 Share Posted April 17, 2008 It's not in my Oxford English dictionary though. I think it may be American English. It's certainly in the online version: http://dictionary.oed.com/cgi/entry/003307...;max_to_show=10 EDIT: Oops! You might not be able to see this link, as it looks like it's via my works subcription. But it is in there! A concurrent post has been automatically merged from this point on. ohmage, n.Electr.Electrical resistance as expressed in ohms. 1909 Webster's New Internat. Dict. Eng. Lang., Ohmage, the resistance of a conductor expressed in ohms. 1943 F. E. TERMAN Radio Engin. Handbk.

Ekij Posted April 17, 2008 Share Posted April 17, 2008 I would consider Ohmage to be slang.I'd use impedance (or resistance if the load is purely resistive). Link to comment Share on other sites More sharing options...
niax Posted April 17, 2008 Share Posted April 17, 2008 In frequency based resistance cases, I believe the proper term is Reactance, normally identified by X (At least for Capacitors and Inductors anyway) Link to comment Share on other sites More sharing options...
Albatross Posted April 18, 2008 Share Posted April 18, 2008 I would consider Ohmage to be slang.I'd use impedance (or resistance if the load is purely resistive).I agree 100% When I was doing my electronics apprenticeship (early 1980's) the terms were quite clear.Resistance & Impedence, measured in OhmsCurrent, measured in Amperes (shortened to Amps by popular usage)Voltage, Potential, measured in Volts.Power, measured in Watts. I'd not heard the term till the past few years, but I understand the usage, based on Wattage & Voltage.Just because something becomes commonplace, i.e. slang, does not make it a proper word, or correct usage.

grizzly Posted April 18, 2008 Share Posted April 18, 2008 Just because something becomes commonplace, i.e. slang, does not make it a proper word, or correct usage. But surely that is how voltage, which you put forward as 'correct usage', must have come about? In the same way as wattage, ohmage & amperage? It (and wattage to a lesser extent) seems to have stuck for some reason (probably because they don't sound as horrible and ungainly as ohmage and amperage).
