This may seem like a stupid question, but never the less I will ask it,
The basic circuit that is made will have a positive terminal and a negative terminal, now the circuit below has only a positive 12V wire,
My stupid question is this, If I had a 12V "battery pack" what do I connect the negative terminal to? the ground
also on a similar note, whilst converting a ATX power pack I noticed that there was only a +5.5V wire if i used this wire alone to light up a bulb what do I connect the opposite wire on the bulb to to complete a circuit?
I always though the ground was for safety if a circuit had excess voltage it would be removed via the ground? Hopefully I am correct in the ground terminals function...
for me this just doesn't make sense.
Thanks for your Ideas
