(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Select the correct expression for ##i_o(t)## for ##t≥0^+##.

2. Relevant equations

##V(t) = V(∞)+[v(0)-v(∞)]e^{\frac{-(t-t_0}{\tau}}##

##i(t) = C\frac{dV(t)}{dt}##

##\tau = RC##

3. The attempt at a solution

I'm a bit stuck on this problem. Specifically, I'm not sure how to deal with the dependent source.

At ##t=0##, the voltage of the capacitor should be 15 volts since the capacitor is directly in series with the voltage source with no branches leading off anywhere.

After ##t=0## the current through the capacitor would be ##C\frac{dV(t)}{dt}##, but I'm sure the dependent source changes things somehow. I'm just not sure how.
