Students combine what they learned about series and parallel circuits to further explore how circuits work.

|Power Supply, Extech (Model #382213)||JE-105A-X12/13||1 per table|
|Holder, light bulb, 5 soldered together||JE 105a Dr. Cumming||1 per table|

If power supplies aren't in 105A they may be on cart JE 105A-016 which is often left in room JE 109. Make sure power supplies are all turned off, the knobs are all turned counter-clockwise as far as they can and the switches on the sides are on V, not MA. The circuits of 5 bulb holders soldered together should be filled with bulbs. Place bulbs in the 3 loose holders as well. Blown bulbs have been finding their way back to the main supply of bulbs, so check all bulbs when setting up the lab.
