Very simple, am I right in thinking that a 2k resistor has a resistance of 0.2 ohm?
No, 2,000 ohms.
That's what the k stands for, same as in everything else.
Beat me to it! Bloody phone...
Yeah the k means 2x10^3ohms.
As with metres, 1km = 1x10^3m
generally speaking:
2k = 2000 ohms
2k5 = 2500 ohms
2R = 2 ohms
2R5 = 2.5ohms
0.2R = 200 milliohm
Great, thanks.
Yep 2K = 2000 ohms
think the resistor colour bands should be red black red
the whatever bannds for tolerance of say 5%
Ohms are one of those units that comes out pretty small for general usage. 1 Ohm is very low, 2k is a fairly small one, 2M even is quite common in electronics.
Conversely, Farads are pretty big units. A 1F capacitor is massive, the big fat ones you see inside things are micro Farads, and pico Farads are common.
