$begingroup$ The battery ends don''t have an absolute voltage (relative to ground) of 1.5V unless the negative terminal is shorted to ground. They have a voltage between the anode and the cathode of 1.5V. The absolute voltage of either end (and your own absolute voltage before touching it) is completely uncertain, and can fluctuate wildly if it is, for example, …
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). $endgroup$ –
Grounding Negative of Power Supply | Information by Electrical ...
It is a 60W 24V power supply. We also use the negative output on the supply for the ground reference on a 0-5V signal, would grounding the negative terminal have any effect on this? Also, the power supply has internal protection and makes a dinging alarm sound when shorted. It is not a fuse, because the power supply is operable when the fault ...
DC Switch on Positive or Negative or Does it Matter?
To avoid confusion, I would put the switches in the positive lead for all circuits just to avoid confusion down the road. You should also have a fuse or circuit breaker in the positive wire too, near the battery, rated no larger than the wire can handle (i.e., if you follow NEC, 14 AWG wire would have a 15 amp fuse/breaker maximum). Any decent ...
