How to make a simple negative power supply

$begingroup$ @Mordecai: if you are using a battery supply, you simply call the mid-point of the battery "Ground" - For example,you could connect two 9 volt batteries in series, and call the connection between the batteries "Ground/Zero Volts", or you could use a single battery to provide the positive supply, and an isolated DC-DC converter ...

dc

This doesn''t make sense to me. The positive part is positive and the negative part is negative regardless of which direction the current flows. If current is flowing into the positive part then the device the plug is attached to is receiving power (would be a little against standard use of these kind of plugs). $endgroup$ –

electrostatics

This is because even though your body is conductive and connected (usually with some non-zero resistance) to the ground, touching only one pole will cause only transient, very quick and very small redistribution of electric charge to get the battery pole at the same potential your body and the ground is, and then current stops.

batteries

Think of a car battery. The negative terminal of the battery is connected to the chassis of the car. So is every electrical device in the car. Everything is also directly or indirectly connected to the positive terminal of the battery. Everything ''sees'' the potential difference between the positive and the negative terminals of the battery.

positive and negative voltages from power supply

The first answer is to get another supply. Tie the + output of that supply to the ground you already have. Now the - output of this second supply is your negative supply.
