Answer Posted / hubert barge
The power circuit begins at the wall. The control circuit comes in over the cable. If you touch the power circuit, you get a shock. If you touch the wire from the cable, nothing happens. The power contains the power to give the light to the television screen. The cable tells it what picture to show. Now, if you look at your Circuit diagram, you will see where the power comes to the computer. It might say +5v or +12v or it could show and input of 110 volts and an output of +5 and +12. There probably is also a -5 and -12 somewhere. Those are your power circuits. They power the entire computer. If you look closely at your wiring diagram, a wire from that goes to every transistor in your computer. The control circuits are likely to go anywhere. They carry data. The power circuits all go back to one point. The control circuits do not.
