Homework Statement

The Attempt at a Solution
(a) No current, so no time constant since C = 0 for it stores no charge
(b) Current immediately is driven through so [tex]\tau = (R_{1}+R_{2})C[/tex]
(c) I pulled the formula out of the book
[tex]I(t) = \frac{\varepsilon }{R}e^\frac{-t}{\tau}[/tex]
But I am not sure what they want after...
