The maximum and minumum Current
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 accross 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 im 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. This is useful - http://www.uoguelph.ca/~antoon/gadge...s/resistor.htm so is this - http://www.csgnetwork.com/resistcolcalc.html |
