Jasmine makes a note card about series circuits. She records the points shown.

\begin{tabular}{|l|l|}
\hline
\multicolumn{1}{|c|}{Advantages} & \multicolumn{1}{c|}{Disadvantages} \\
\hline
(1) They are simple to design and build. & \begin{tabular}{l}
(2) Each source of current used adds \\
more current to the circuit. \\
(3) The more bulbs are added, the \\
dimmer the bulbs are. \\
(4) If one bulb goes out, all bulbs go out.
\end{tabular} \\
\hline
\end{tabular}

Which change will correct the error on her note card?

A. Switching the headings on the columns
B. Adding the title Parallel Circuits
C. Moving point (2) into the Advantages column
D. Moving point (4) into the Advantages column



Answer :

Let's analyze the points recorded by Jasmine and see which change will correct the error on her note card.

Advantages:
1. They are simple to design and build.

Disadvantages:
2. Each source of current used adds more current to the circuit.
3. The more bulbs are added, the dimmer the bulbs are.
4. If one bulb goes out, all bulbs go out.

### Evaluating the Points:

1. Advantage: “They are simple to design and build.”
- This is correctly placed under advantages. Series circuits are indeed simple in design.

2. Disadvantage: “Each source of current used adds more current to the circuit.”
- This seems like an advantage rather than a disadvantage. It suggests that adding more power sources increases the current, providing more power.

3. Disadvantage: “The more bulbs are added, the dimmer the bulbs are.”
- This is correctly placed under disadvantages. In a series circuit, adding more bulbs indeed makes each bulb dimmer because the total resistance increases.

4. Disadvantage: “If one bulb goes out, all bulbs go out.”
- This is also correctly placed under disadvantages. In a series circuit, the circuit is broken if one element fails, causing all elements to stop working.

### Considering the Answer Choices:

1. Switching the headings on the columns: If we switch the headings, it will incorrectly classify the points. Currently, points (3) and (4) are legitimate disadvantages and should stay under disadvantages.

2. Adding the title Parallel Circuits: Changing the title won’t correct the error in the points Jasmine recorded.

3. Moving point (2) into the Advantages column: This makes sense because having more current from each source could be considered beneficial.

4. Moving point (4) into the Advantages column: This would be incorrect, as point (4) is clearly a disadvantage, not an advantage.

### Correct Change:
The correct change to Jasmine’s note card to fix the error would be:
- Moving point (2) into the Advantages column.

Therefore, the correct option is moving point (2) into the Advantages column. This change will correctly categorize point (2) as an advantage, leaving the disadvantages accurately described as they are.
