**Circuits question!?**

A series RC circuit consists of a 550-µF capacitor (initially uncharged) and a 12-kOhm resistor. The combination is connected across a 12-V battery; 3.0 s later, what is

(a) the charge on the capacitor,

(b) the current in the resistor?

I really just want to know what equations I need to use.. I'm sure I can work it out knowing the right way to do it.
