That's a rather odd statement.I wish the "ohm" unit of measurement was never introduced.
Not an odd statement at all. Why do we use miles/hr? Why don't we rename it to the Ford, or the Stanley or anyone else associated with car or train travel to commemorate what made this unit of measure important to the English-speaking (and English measuring) world? Answer, because naming the derivative unit makes any estimate of changes to time or distance less obvious TO THOSE NOT USING THE UNITS ON A DAILY BASIS. Have some empathy, think about a student leaning for the first time instead of your own view after a 25-year to 40-year history with the term.That's a rather odd statement.
Any other terms you want to eliminate?
Someone else on these sites wants to eliminate the decibel.
Is all this because you do not feel at ease with it, gophert?I wish the "ohm" unit of measurement was never introduced. It's like the speed unit of Mach. Completely unhelpful to just have a speed term, or a resistance term unless you only need to compare speeds or compare resistances.
Speed is really a derivative term a change in distance over a change in time. It becomes very easy to do the math and intuitive to cancel units of measurement and appropriately multiply, divide and estimate changes when expressed as Distance/Time.
Ohm should be expressed for what it is, Volts/Amp.
Example, I have a 12 volt supply and an LED with Vf = 2 requiring 0.5 amps. How much current limiting do I need?
10V/0.5A=20V/A resistance. It becomes much easier to teach someone electrical concepts.
Well I think most prefer that extra layer.referring to resistance as volts/amp doesn't get rid of ohm's law, it just avoids an unnecessary layer of abstraction
My resistors generally have color codes or abbreviated numeric codes on SMDs and don't specify "ohms". Which brand do you buy?Well I think most prefer that extra layer.
So you would label resistors as volts/amp rather than ohms?
It's even easier to say a 10k resistor.Seems a lot simpler to say I need a "10k ohm resistor" compared to I need a 10k volts per amp resistor.
and wouldn't a 8 volt/amp speaker make it easy to calculate the power if you have a +/-45v DC (~32VRMS max signal)?"I want 10" 4 speaker"
A four speaker cabinet?
A 10" empty cab for your 10" speaker?
"I need a roll of 50 coaxial cable".
50ft? 50 metres? .5 inch?
I can think of numerous places a unit for resistance is explicitly required to avoid confusion.
So since schematics do not need to use Farads for capacitor values or Henries for inductance values, then I suppose those can be eliminated also.If you're talking schematics, even those are commonly just numeric or use the generalized "R" notation in most cases.
No. But they can if you want.So since schematics do not need to use Farads for capacitor values or Henries for inductance values, then I suppose those can be eliminated also.
As speakers (and many other things) use Ohms to represent impedance ?? No.and wouldn't a 8 volt/amp speaker make it easy to calculate the power
Yep - it's like he's trying for the most stupid posts ever!.As speakers (and many other things) use Ohms to represent impedance ?? No.
Try and order some 50 volt/amp coax!
Doh.
