What happens if you connect car batteries together?
When connecting batteries: Never cross the remaining open positive and open negative terminals with each other, as this will short circuit the batteries and cause damage or injury.
Is it bad to put two power supplies together?
This is a circuit diagram of a computer power supply I added it to give you some help about your experiment: Putting two power supplies of equal voltage together is not likely to result in a good distribution of current. Putting two power supplies of different voltage together is an even more terrible idea.
Is it bad to connect two batteries in parallel?
But connecting two batteries of different voltage ratings in parallel is disastrous. Connecting batteries of different voltage ratings in series is not a problem at all. Voltage rating of the series combination is, summation of the voltage ratings of the all the batteries.
What happens if I connect two switching supplies?
With two switching supplies though, as W5V0 has noted, the resultant voltage will likely be the higher of the two, as the lower rail cannot sink current (due to the diode) and will effectively look high impedance to the 12V rail. So all that should happen (see below) is the lower rail will rise to the potential of the higher rail.
What happens if you put two different voltages together?
Putting two power supplies of different voltage together is an even more terrible idea. Either the lower voltage supply shuts off (and is useless) or it sinks current. If it is designed to sink current, it will reduce the available current from the higher voltage supply.

What happens when you connect two batteries in parallel?
two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah). four 1.2 volt 2,000 mAh wired in parallel can provide 1.2 volt 8,000 mAh (2,000 mAh x 4). But what happens if you wire batteries of different voltages and amp hour capacities together in parallel?
