Electric circuits and diff.eq

  1. Feb 8, 2006 #1
    Hi Guys... i'm trying to learn diff.eq on my own and i'm stuck on a problem and I don't even know where or how to begin:

    the problem is: the pacemaker shown in the figure (first attatchment) is made up of an electric battery, a small capacitor, and the heart which functions like a resistence in the circuit. When the commuter S connects to P the capacitor charges, when S is connected to Q the capacitor discharges sending an electric shock to the heart. During this time the electric tension E applied to the heart is given by: (second attatchment).

    The resistance and the capacitance are both constant...
    what is:
    E(t)= ? E(t1) = Eo

    Would it be a first order linear equation?
    Is it homogenous?
    What would be the value of the initial voltage?

    - i translated it directly from spanish so if further clarifying of the problem is needed please let me know.
