When two resistors are in series, what is it called?

• A. A Parallel Circuit
• B. A Series Circuit
• C. A Mixed Circuit
• D. A Short Circuit

Answer: (B)

When components are connected end-to-end in a single path, the arrangement is a series circuit. In this setup, the same current flows through each resistor because there is only one path for charge to take. The total resistance is simply the sum of the individual resistances, so two resistors in series have a total equal to R1 plus R2. The voltage from the source divides across the resistors in proportion to their resistances, but the current remains the same through both. This differs from a parallel circuit, where all components are connected across the same two nodes so the voltage is the same across each resistor and the currents add. A short circuit is a low-resistance path that bypasses components, not a simple series connection. A mixed circuit contains both series and parallel parts.
