    Hello,

    I found this in my E-mails:

    As I do not answer E-mails and PM's I posted it over here.
    That way others can respond also at it.

    Actually, you can start from E = IR, which defines voltage (E) as the product of current (I) and resistance (R). If you accept that, then finding any one of the quantities as defined by the other two is simple algebra. So, if E = IR, then I = E/R, and R = E/I.

    The lamp is not the output.
    The two resistors and the lamp are in series so they are all the output and all pass exactly the same current.
