• A. Mixed 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 arrangement is a series circuit. In a series circuit, the same current flows through every component because there’s only one path for the electrons. The total resistance is the sum of all resistances, so adding more components increases the overall resistance and tends to reduce the current for a given voltage. The source voltage is divided among the components, with each drop depending on its resistance. If any part breaks the circuit, the current stops everywhere. This is different from a parallel circuit, where current can split into multiple paths and each path can carry its own current while the voltage across each path remains the same.
