Series vs. Parallel circuits

Posted: April 30, 2013

Series versus Parallel Circuits Laboratory

 

Procedures:

1)     Obtain a light bulb, a battery and a piece of wire.

2)     Get the light bulb to light in as many ways as possible and describe and diagram them in your data section.

3)     Using a second piece of wire repeat procedure two, describe and diagram in data section.

4)     Using two batteries, set up a parallel circuit (+ to +, – to -) and get the light bulb to light. Diagram your circuit and describe the results, especially the brightness of your bulb.

5)     Using the same two batteries, set up a series circuit (+ to -) and diagram and describe this circuit, especially the brightness of the bulb.

6)     Get a second light bulb and more wire. Using this, set up a parallel circuit using the two light bulbs as different paths in the circuit. Diagram and describe this circuit.

7)     Take one bulb out of its holder and describe the change in the circuit.

8)     Using the same equipment as in six, set up a series circuit with both light bulbs connected in the same line. Diagram and describe this circuit.

9)     Take one light bulb out of its holder and describe the effect on this circuit.

10)                      Return all equipment to your teacher and clean up lab station.

 

Conclusion:

1)   What are the differences between a parallel and a series circuit?

2)   What happened when you removed light bulbs from the different circuits? Why?

3)   What did you learn?

4)   Problems or Improvements
