first of all, let me apologise for my inexperience with electronics.
Now that's over with, I'm trying to follow a guide that specifies the use of a specific temperature sensor with an output of 5v DC. The problem is that the sensor I currently have provides different values and that a resistance of 14.2k ohms is required. The problem I have is that this step provides no further information. The actual step is as follows: -
The outlined box above, which currently is set to 14.2, represents the resistance in to be added in parallel
I'd like to know how to obtain this specific resistance to place between the sensor and the controller that reads this value. I assumed I could build the resistance in a series.
I am under the impression that resistors can be placed in series, i.e. I could add a 10k ohm resistor and a 4k ohm resistor and then a 0.2k ohm resistor. Forgive my ignorance here, please, if this is completely idiotic. So I went to http://www.crownaudio.com/ohms-law.htm and entered 14200 and 5 into the respective fields and it specified that the watts was '0.00176'
Does this mean that when shopping for resistors, I can buy: -
2.2k - 0.6w
10k - 0.6w
2k - 0.6w
I assume I need the same wattage for all but as above, adding all the resistances in series will create 14.2k ohms but they look so flimsy.
