In a series circuit, the current is what in all components?

• A. The current increases as it goes around the loop.
• B. The current is the same in all components.
• C. The current only flows if there is more than one path.
• D. The current can disappear when energy is stored.

Answer: (C)

In a series circuit, there is only one path for the electric charge to follow, so the same amount of charge passes through every component each second. That means the current is the same in all parts of the loop, no matter how many components are in series. You can think of it like a single candle wick feeding a line of candles: the same flame (current) travels along the entire string. The total resistance in a series circuit is the sum of the individual resistances, and the current is determined by I = V / R_total. If the circuit is opened anywhere, the current stops everywhere because the path is broken. The idea that current only flows when there’s more than one path describes parallel circuits, not series. Saying the current increases around the loop isn’t accurate for a series circuit, since the current remains constant along the path. The notion that current can disappear when energy is stored mixes transient behavior (like charging a capacitor) with steady-state current; in a steady DC series circuit the current that remains in the loop is the same through every component.
