## WARNING: To do this you need to plug the adapter into the wall. Be sure that you do not touch the two wires together, this will short out your power supply. If it is easier, use two of the alligator cable to cover the free ends of the wires.
##Is the positive wire labelled in any way? Attach a red alligator cable to the positive wire, and a black alligator cable to the negative wire. This is the standard color code for positive and negative wire.
# Using one red and one black alligator clip cable and a short length of red and black hookup wire, connect the positive and negative lines from the power supply to the appropriate power buses on the breadboard.
# Check that you were correct using a multimeter or bulb/resistor combo. (The bulbs are 6V bulbs, we have a 12 Volt supply. How can we see that current is flowing without burning the bulb out?)
