ohms question

[the pict]

In a recent post of mine about alarms ohms were expessed thus 6k8, I have been reading up on alarm systems and this comes up regularly 10k I understans but 6k8. 7k2 etc at first I thought it mean 7.2Kohms etc but now I am not so sure

You are right.
Also, eg 1R5 = 1.5 ohms

Learn something new everyday :cool3:

cheers Archy, reminds of the refrigeration course I did where if a chill room operated at say between 0c and 4c the differance is expressed in kelvin IE TD= 4 degrees K. beats me why no one in the field used it just the boffins

I suppose using deg K implies coldness.
Can't get much colder than 0[SUP]o[/SUP]K!

possibly the same boffins who think that celsius is identical to centigrade.

You of course have 2M0/V which would be excellent for non-loading of outputs

It is not degrees kelvin it is just Kelvin (pedant:crazy:!)

Lol, Where did Lux come into it ?
We have Kelvin, Celsius, centigrade. We have Ohms and now we have Lux.

You could say we have now seen the light !

I've seen the light, it's Sunday, time for the pub!

I can now see the beer replies in context

I alway thought it couldnt get ANY colder than 0 deg K
Just got back from the pub BTW.
