If all parts are connected end to end to provide a single path for current, what type of circuit is this?

• A. Open Circuit
• B. Parallel Circuit
• C. Series Circuit
• D. Combination Circuit

Answer: (C)

When all parts are connected end to end to provide a single path for current, the circuit is in series. In a series arrangement, the current that leaves the source flows through each component in turn, so the same current passes through every part. The total resistance is the sum of the individual resistances, so adding more components increases the total resistance and lowers the current for a given supply voltage. If any part opens or is removed, the path is broken and current stops throughout the circuit. This is different from a parallel circuit, where current divides among multiple paths, and a combination circuit, which mixes series and parallel sections.
