Conclusion for Parallel Circuit Lab

CONCLUSION FOR PARALLEL CIRCUIT LAB Directions: Answer each question in a complete sentence. 1. State 3 facts that are true and only true of all parallel circuits.

2. State what the Voltage bar graph in Part II is showing you in a parallel circuit and how is this different from the pattern of voltage readings you got in the Series circuit lab?

3. Look at the Current bar graph for Part III. A. What is the main or full current reading in amps? B. What are the individual load current readings? C. Add up the load currents and state their total amps. D. Calculate the % error between the Main current and the total of the load currents.

Difference between Main current and Total current / Main current x 100

4. Look at the Current bar graph for Part IV: A. What is the main or full current reading in amps? B. What are the individual load current readings for each different load? C. Add up the load currents and state their total amps. D. Calculate the % error between the Main current and the total of the load currents. : Difference between Main current and Total current / Main current x 100

5. Why are the Current readings for the loads in Parts III very similar, while in Parts IV, the current readings for the loads are different?

6. Look at the Current bar graphs for Part IV and Part V. A. In Part IV , which load is resisting or blocking the most current flow? How do you know? B. In Part V , which load is offering the least resistance? How do you know?
