Which statement describes a Series circuit?

• A. The same current flows through all components.
• B. The same voltage flows through all components.
• C. There is no current in a series circuit.
• D. Components share the same resistance.

Answer: (A)

In a series circuit there is a single path for the current, so the current that leaves the source must pass through every component in turn. That means the same amount of current flows through each component, no matter how many elements are in the loop. This is the statement that best describes a series circuit because it captures the fundamental behavior: current stays constant along the entire path. Voltage, on the other hand, is shared among the components. Each component drops a voltage proportional to its resistance, and the sum of all those drops equals the source voltage (V = I × R for each component, with the total resistance being the sum of individual resistances). So the voltages across components aren’t necessarily equal. There is indeed current in a complete series circuit, and adding more components changes the overall resistance, not the equal distribution of resistance.
