Description
This may seem like a lot of work but it really isn't the attachment (4.5B Circuits Directions i) is added to help you visualize on what to do for this lab which means you dont have to complete it.

Explanation & Answer
Please see the attached file containing your solutions. Please let me know if you have any questions regarding the material.
Activity B (Series Circuits) – Observations
If you increase the voltage in the circuit, the current will also increase. Likewise, if you decrease the
circuit voltage, the current also decreases.
While holding voltage constant, adding more light bulbs in series increases the resistance in the circuit,
which ultimately reduces the current in the circuit. All light bulbs will have the same brightness in a
series circuit.
In a series circuit, the current does not change. It remains constant at all points throughout the circuit.
Activity C (Parallel Circuits) – Observations
Adding additional bulbs in parallel changes increases the amount of current in the circuit.
In a parallel circuit, the current is not constant. The current varies when measured along different wires.
Conclusion
1. The circuit voltage remained constant in the experiment. As you added more light bulbs, you
changed the overall resistance in the circuit, which ultimately caused the current to decrease.
With a series circuit, if one bulb were to burn out, or be removed, the flow of electricity would
stop and all lights would go out.
2. The circuit voltage remained constant in the parallel circuit. The current varied across different
branches within the circuit, and changed as new bulbs were added in parallel. As more bulbs
were added, the current increased. With a parallel circuit, if one bulb were to burn out, or be
removed, the flow of electricity would continue along the other branches, so the remaining
lights would stay lit.
