meaning of 2k2
2k2 means 2200 (the K is for Kilo) so you need a 2200 ohms resistor (or for ease of future reading these numbers, 2.2kiloohms).ts done like that because little decimal points. get lost in print. Jack A Lopez 3 years agoReply. A 2k2 resistor, is a 2.2K resistor, is a resistor with a resistance of 2.2*10 3 = 22*10 2 = 2200 ohms = 2200 Ï. This particular resistor is easy to identify visually because it has three red stripes on it.
