The maximum and minumum Current

[POLISH_Soldier]

A resistor has the following color code red, red, orange, gold. Determine the maximum and minimum currents, in mA, you should expect to measure when a 16 V source is connect across the resistor.

I dnt no if this is right...
22000 Ohms +- 5%

22000 + 5%= 23100ohms--->23,1K MAX
22000 - 5%= 20900ohms--->20,9K MIN

Now i dnt no if the following is good. Since I am using a 16V source i have to Use ohms law?
and what i got for both is a

-maximum of 0.69mA
-Minimum of 0,76mA

22000 Ohms +- 5%

Red = 2, so Red Red is 22.

Orange = 3, so the multipliyer is 1000 or 10³,

and the nominal resistance is 22000 Ohms. or 22 kOhms.

the tolerance band is gold, so +/- 5%


Use V/R to get I, and min I = V/ max R.

Thx that's what i had and it seems right :) thanks again
