    I really need help. I actually don't know how to do this

    Use Kirchoff's rules to determine I1, I2 and I3 for the following circuit:
    Circuit figure
    https://chip.physics.purdue.edu/protected/Prelab221img/e4pp2.jpg

    E1 = emf = 9 V
    r = internal resistance = 1.5
    R1 = 5
    R2 = 15
    R3 = 16.23

    Find I1, I2, I3

    I1 - .86. but I don't know what to do after.

    Please Help!

    Hello ,
    Are the three resistors R1 , R2 and R3 in parallels or series or in combination of these two ?
    Once we know this we will be able to find out the current in all the three resistors.

    I cannot open the link to that image. The site is asking me to sign up ! Please upload that to any other site or attach it here only.
