Posted by on .

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 9 amperes when the resistance is 940 ohms. What is the current when the resistance is 580 ohms?

Thank you yet again. Almost through with this part of the class thank goodness!

  • ALG WORD PROBLEM - ,

    i = k/r
    9 = k/940
    k = 8460

    i = 8460/r
    i = 8460/580
    i = 14.6 amps

    by the way, k is the voltage V

  • ALG WORD PROBLEM - ,

    E = I*R = 9 * 940 = 8460 V. = Supply voltage.

    I =E/R = 8460/580 = 14.6 Amps.
