Homework Help: Battery, emf , r, and voltage

  1. Jun 4, 2008 #1
    1. The problem statement, all variables and given/known data

    A torch battery has an emf of 6.0V and an internal resistance of 1 Ohms. What is the voltage measured by a voltmeter connected across the terminals of the battery, when the battery is connected to a bulb that draws 0.5 A from the battery?

    Anyways thanks I solved it.

    For future reference, if you're satisfied that you've figured out the problem and are satisfied with the answer, edit your thread title to include the word "[SOLVED]" at the start of it. This will let the helpers know that you're all right and they won't need to open your zero-reply thread. Thanks!
