Given a source voltage, and a capacitor value, is there a formula that will show the maximum current that the capacitor will draw until it is fully charged?



a very large value capacitor will suck a lot of current and take some time to charge. whereas a very small capacitor will draw less current and charge much faster. this current draw is what im solving for. thank you!
 
Hi.

You need to specify the cap's internal resistance together with total wire resistance and internal resistance (or impedance) for voltage source.

From an ideal voltage source, a direct connection to a cap will give infinite start current.
