Basic question on resistance

  1. Jan 25, 2009 #1
    1. The problem statement, all variables and given/known data

    Question 5

    2. Relevant equations

    3. The attempt at a solution

    For a) I put that because the circuit isn't closed there's no current.

    for b) I can see that the total resistance would be the sum of
    [itex]168k\Omega + R_2[/itex]

    [itex]R = \frac{V}{I}[/itex]
    [itex]R = \frac{3.4}{I}[/itex]

    I don't know the current. I'm new to this so I don't really know how to solve. I think an example would help.

    You have enough information to get current across the resistor.
