Homework Statement
You have an RC-circuit with emf E, resistance R, and Capacitance C. However, R = R(t) = R_o(t/tao+1)^-1, where R_o is the intitial resistance. Assume that other than the time-dependent resistance, the circuit behaves normally.
Homework Equations
Show that during discharge the charfe at time t is given by
q(t) = q_oe^{-t(t/2tao+1)/R_oC} where q_o is the initial charge on the capacitor.
The Attempt at a Solution
I know to find q(t) of a simple RC-circuit you need to use basic differential equations. (a course which I have not taken yet). I've tried to simply substitue R(t) for R in the equation
q(t) = q_oe^(-S dt/RC)
(the "S" is the great s for integration, I'm not sure how it should be notated.)
This isn't working though.
