What I'm trying to work out is how a power bank output current affects the calculations of my circuts.

I know voltage = current * resistance

I know that the current across a serial circuit resister the same

I know that a current across a parrall circuit is the tottal of the current across all the resisters in parrall with eatch other.

But say I had a serial circuit with a 1k, 10k and 2k resister with a 9v batterey how would a powerbank with a 1amp output change the calculations of current in my circuit from a powerbank that outputs 2 amps
