Circuits question?

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

    What equations do you know that concern RC circuits, or circuits in general?

    I don't know any thats way I'm asking for the equation/s. I know a little about the Kirchhoff's current laws.

    That's fine, you can use Kirchoff's laws to solve the problem. How would you apply Kirchoff's loop rule to this circuit?
