How do you calculate the amps in a capacitor if you know the voltage and number of farads?

A capacitor with 25 volts and 4,700 uf has how many amps, and how many amps would that be if I had four in parallel?

Capacitors don’t "have amps". You need to explain this better.

If you mean how much current you can draw from a charged capacitor, it depends on the load. Yes, if you had 4 in parallel, you would be able to draw more current, if the load were adjusted to call for that much current. If the load stays the same, then 4 caps would supply the same current as 1 cap, it would just last four times as long.

But the important part is that the current is NOT determined by the cap, it is determined by the load you put on it.
