Homework Help: Finding value of R

  1. May 23, 2010 #1
    I have to find the value of R

    v1 = 30V

    this is how i did it

    since R is in parrallel i juts put that R/2

    R/2 = 30V/10A = 3ohms/2 = 1.5ohms

    is this correct?

    Try it again, multiplying both sides by 2.

    Calculating (using valid maths) is probably better, but think about how the current will split through each branch given equal resistance.

    Then use Ohms Law.
