# Connect the positive and negative rails running along the top and bottom of the breadboard. (Red --red wire for positive and black wire for negative(pic). # Use the continuity setting on your multimeter to check the continuity connectivity of the positive and negative rails. (pic).# Clip the end of the power adapter off, save saving enough wire with the plug to reattach it reconnect the two later in the semester (i.e. do not cut it off clip the wires too close to the plug or you will not be able to reattach and solder it the two later)# With the DC voltage setting on the multimeterin the appropriate range, identify indentify which is the positive and which is the negative wires coming wire comeing from the adapter. Is the wire labelled in any way? Tie a know knot in the positive wire, so that it is shorter then the other (preventing a short-circuit), and so you know which . This is whichalso an easy means to distinguish between the two. # Using one red and one black alligator clips clip and a short lengths length of red and black hookup wire, connect the positive and negative power lines from the power supply to the appropriate power buses on the breadboard. # Check the current flow with that you were correct using a multimeter and or bulb/resistorcombo. (The bulbs are 6V bulbs, we have a 12 Volt supply. How can we see that current is flowing without burning the bulb out?)
