When comparing resistors in series vs. parallel, which configuration generally leads to a higher overall resistance?

• A. Series configuration
• B. Parallel configuration
• C. Both are equal
• D. Depends on the resistances

Answer: (A)

In a series configuration, resistors are connected end-to-end, meaning the total resistance is the sum of the individual resistances. The equation governing total resistance in series is straightforward: R_total = R1 + R2 + R3 + ... This approach ensures that the total resistance increases as more resistors are added, leading to a higher overall resistance. In contrast, when resistors are configured in parallel, the relationship changes. The total resistance in a parallel arrangement is calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ... This results in a lower overall resistance since current can flow through multiple paths, effectively decreasing the total resistance. Thus, the series configuration is characterized by a higher total resistance due to the additive nature of the resistors, confirming that selecting the series configuration typically results in a greater overall resistance compared to the parallel arrangement.
