The maximum and minumum Current

  1. Sep 19, 2007 #1
    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
