A “complete circuit” is needed for electricity to flow through a circuit. This can be accomplished by using a conducting wire to connect either the positive or negative terminal of a power supply to a circuit element, and then connect a wire from the circuit element to the other terminal of the power supply.
In this activity you will construct a complete circuit that causes Christmas tree light bulbs to glow and then investigate the brightness of the otherwise identical light bulbs as additional bulbs are connected in various circuit arrangements.
Objectives:
· Create a working light bulb circuit
· Discover what happens to the brightness of otherwise identical bulbs
a. as more and more are connected in series,
b. as more and more are connected in parallel,
c. as multiple bulbs are connected in combination arrangements
Equipment:
Size D dry cells, cell holders, connecting wires, Christmas tree lights
Procedure:
Note: Screen shots of circuits shown in this document were taken
from a free electrical circuit simulation found on the World
Wide Web at http://www.physicslessons.com/exp22b.htm.
