To distinguish the different purposes of text, this web site uses the following conventions:
fixed font, blue, in a box - used to indicate where you need to replace the text with your own specific values: e.g. share name, etc.
fixed font, black, in a box - used to indicate where you need to type a command.
proportional font, black - used in descriptive text to indicate an operating system command, keyword or filename.
italic font - text taken verbatim from elsewhere - usually book synopses.
A common way to denote resistor values is shown below. This notation avoids using a decimal point, which may be mis-read on photocopied drawings or small components. It also avoids multiple zeroes that can be mis-counted and take up space. The general format is xQy where x is the integer part of the number, y is the fractional part and Q is a multiplier that shows the location of the decimal point. Multipliers are: R = 1, K = 1000, M = 1000000. Some examples:
|100R||100.0 x 1 = 100Ω|
|4K7||4.7 x 1000 = 4700Ω|
|1R||1.0 x 1 = 1Ω|
|R1||0.1 x 1 = 0.1Ω|
|R01||0.01 x 1 = 0.01Ω|
|1M||1 x 1000000 = 1000000Ω|
A similar notation is often used for low voltages. Again it uses the format xVy where x and y are the integer and fractional parts and V shows the location of the decimal point. In Europe, the decimal comma is used instead of a decimal point and this notation avoids confusion by omitting the point or comma completely. There is no multiplier. So 3V3 means 3.3V, 1V8 means 1.8V.
