Hey guys,
Been getting into home automation as of late, but am weak on the electronics side, hoping for a bit of direction to build my foundation.
I have a basic question regarding supply multiple DC devices from a single DC power supply.
Scenario is:
INPUT:
12V 5A DC power supply DC plugs
OUTPUT:
2x 12V 1.8A DC 2wire fans
1x 12V 1A water pump
If I only have 1 of the 3 equipment running, then does the water pump only take the 1A it needs. I figure with the other fans seen as an open circuit would then mean the 3.6A would also flow into the water pump by KCL.
So correct me if im wrong, I'd need to setup a set of parallel resistors for the case when the switches are open.
If that makes sense?
