Homework Help: Resistance and Temperature

  1. May 25, 2013 #1
    1. The problem statement, all variables and given/known data

    How does does resistance vary with temperature for an Ohmic conductor and filament?

    2. Relevant equations

    3. The attempt at a solution
    So what I know is that resistance(Ohms) against temperature(K) for an Ohmic conductor is directly proportional with the graph passing through the Origin and being a straight line.
    And for a filament, the resistance is directly proprtional for a range of temperatures and then decreases with the graph having a decreasing gradient.
    Note this is Grade 11 level. I HAVE AN EXAM :(
