SAT Practice Passage: Series Circuits

According to the passage, what happens to the total current in a series circuit if the resistance of one component increases?

• The total current remains the same
• The total current increases
• The total current becomes negative
• The total current decreases

The passage uses the analogy of holiday lights to illustrate:

• The impact of technology on society
• The significance of personal achievements
• The importance of material possessions
• Interconnectedness and the importance of each individual's contribution to the whole

Based on the information provided, which of the following statements is TRUE about series circuits?

• They offer the advantage of redundancy in case one component fails.

• They are less efficient than parallel circuits in distributing current.

• The total voltage across the circuit is equal to the sum of individual voltage drops across each component.

• Increasing the number of components in the circuit always increases the total resistance.

The passage suggests that understanding series circuits is important because:

• Parallel circuits are more common in everyday devices
• Series circuits are too complex to analyze
• It allows for safe and effective use of electricity.

• Understanding series circuits is not relevant to electrical engineering

The author's primary purpose in this passage is to:

• explain the dangers of electrical circuits

•  advocate for the use of series circuits in everyday life

•  provide a comprehensive comparison of different circuit types

• offer a clear explanation of how components interact in a series circuit
