I'm just curious if it's possible to power 2 devices at different voltages with a set of batteries while making sure that the 2 devices makes use of all the batteries. I have here an illustration of the connection that I would like to get verified.
Each battery is rated n volts
An Alternative Illustration^
The solution that I propose is to connect 4 batteries in series first to power 1 device. Then since there can be 2 sets of batteries in series already I can connect these sets in parallel for the Voltage to not add up. However, just by looking at the circuit I think some portions are actually shorted.
Any help would be appreciated. Please don't be harsh if this is a dumb question.
