Homework Help: Potential drop across each resistor

  1. Jul 17, 2011 #1
    1. The problem statement, all variables and given/known data

    Two resistors, R1 and R2, are connected in series across a potential difference, ΔV0. Express the potential drop across each resistor individually, in terms of these quantities.

    3. The attempt at a solution
    R1 + R2 = Req
    I = V0 / Req

    drop at
    V1 = V0 / (req) * R1
    V2 = V0 / (req) * R2

    i think this right?

    That should be correct assuming you mean that V1= (R1/Req)V0 and similar with V2.

    This sort of circuit set up is also referred to as a potential divider or voltage divider.
