= = =PhySci Friday, October 10, 2008= Review Series and Parallel Circuits

Circuit Activity

 * 1) Use the bulb panels and wires to set up a “series” circuit.
 * 2) How bright are the bulbs?
 * 3) Loosen a bulb. What happens?
 * 4) Set up a “parallel” circuit.
 * 5) How bright are the bulbs?
 * 6) Loosen a bulb. What happens? Try a different bulb. What happens?

__Procedure A__:

 * 1) What happens to the brightness of each light as you add one more light to the circuit?
 * 2) Why or why not do you think the brightness changed?
 * 3) Draw a complete circuit diagram of the finished circuit.

__Procedure B__:

 * 1) What happens to the brightness of each light as you add one more lights to the circuit?
 * 2) Why or why not do you think the brightness changed?
 * 3) Draw a complete circuit diagram of the finished circuit.
