Cautions:

Do not use an ohm–meter in a circuit connected to a power supply.

Capacitance codes:

There are only uF and pF. If the number is an integer greater than 1 (including any of the complicated codes referenced above) it’s in pF. If the number is less than one, it’s in uF, unless it’s bigger than 1 uF, in which case the cap is likey to be so monstrously huge that there is plenty of room to write “10 F - 2500 V — STAND BACK 100 FEET” on the side of it. For more inforamtion (on the letters, for instance, "k" does not stand for "kilo"): http://wiki.xtronics.com/index.php/Capacitor_Codes
