A 1.5e-6 F capacitor is connected as in fig. 31-10 to an AC generator with Em=30 V. What is the amplitude of the resulting alternating current if the frequency of the emf is (a) 1kHz and (b) 8kHz?

I have no idea where to begin. I don't even know what they are asking for in this problem.

Does $$\frac{1} {2 \pi f c}$$ help?

If you can show me how to do the entire problem that would be great.

PF guidelines are that you need to show your attempt at a solution.
Also you should have posted it in the homework section.
