The resistance in an electric circuit varies inversely with the current. If the resistance is 12 ohms when the current is 4 amps, what is the resistance when the current is 8 amps.?

  • Algebra -

    R = kI, where k is a constant.
    put in the given values
    12 = k(4)
    k = 3

    Now you have your equation to answer the last part
