Hello all !
Although I've always been able to interpet schematics with no problem before now - there are some now beginning to appear that have component identifications I am unfamiliar with.
For Instance: On one schematic there are capacitors marked as "47n" which I'm pretty sure means 47 nanofarads - but others marked "4n7" which I have not a clue what that means.
On the same schematic there are resistor values marked as "3k3" and "1k8" that I don't understand. I know "3k" means 3000 ohms - but what does "3k3" mean? Also one marked "270R". Is this supposed to mean 270 ohms? If so, why the "R" when other resistors on the schematic do not have the "R".
I feel suddenly very stupid seeing these designations - like I have been in a dark hole somewhere and am no longer able to understand. I hope someone will take pity on me and try to explain these designations I've not seen before.
Thanks for your consideration and patience with what may seem to be a very stupid question.
