Solve this equation

  1. May 8, 2006 #1
    Hi,

    Can someone give me a hint for solving this equation?

    V0 - dQ(t)/dt * R(t) - Q(t)/C(t) = 0

    Thanks,

    Mica

    What have you done so far? Have you tried solving the homogeneous solution first?

    Sorry, I have long time that I did not solve a differencial equation. Can you give me its form?

    thanks,

    What you have is a linear differential equation with variable coefficients. The solution depends strongly upon what Q(t) and R(t) are. You might be able to use Laplace Transform to write a "formal" solution in terms of integrals of Q(t) and R(t)
