Potential divider question

  1. Sep 4, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    V=IR R=ql/A

    3. The attempt at a solution
    I chose option A as current prefers to flow through the path of least resistance.

    Can you frame your thinking in terms of potential difference across each lamp, and how this varies as the slider is moved from Y to X?
