    SRI = n1-n2
    40 = 63.9 - n2
    n2 = 23.9
    23.9 = 10 log(I/10^-12)
    2.39 = log(I/10^-12)
    245.5 = I/10^-12
    I = 2.455*10^-10

    Can anybody explain what goes on in the bold part above. Thanks

    23.9 = 10 log(I/10^-12)
    ......................... divide both sides by 10
    2.39 = log(I/10^-12)
    .......................... 2.39^10 = 245.4708915685 ish (both sides to power of 10)
    245.5 = I/10^-12
    .......................... multiply both sides by 10^-12
    I = 2.455*10^-10
