Power circuit= we deliver or draw bulk power say in power system mw

control circuit: our power circuit equipment is controlling by small range of power .

Answer / b. salazar

The power circuit is the circuit that begins at the disconnect, travels through the controller to the machine. The control circuit could be a lower voltage which goes to the switches and relays which determine the order that the machine operates. The control circuit provides power to the controller and when the contacts close, connects the power circuit to the machine and turns it on or off.

Answer / 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.
