My question is this: Suppose, I have a 10A power supply. If I connect equipment that needs 5A to this source, the source will send the 10A that it has or is the equipment that will" pull "the 5A that will he need it and other 5A will be "available"?
If the source has 10 A available, connecting a device that needs 0.1, 1 or 5 A, it will "pull" current only what it needs to function. If we have a 10 A source, for example, we can connect two devices that need 5 A at the same time, since each one will only drain from that source the 5 A that it needs to operate.
