Homework Help: What will be the potential difference?

  1. Nov 13, 2006 #1
    This is my first time on Physics Forum, so if I post this question at the wrong place please don't be annoyed.

    I am a Grade 9 student and I came upon this question and don't know how to solve it:

    An ammeter gives a reading of 5A when a switch was closed for 20 seconds. If this battery has 1000C of charge, what would the voltmeter read? :confused:

    Please help :redface:
