In a series circuit, which statement about current is true?

• A. The current is the same through all components.
• B. The current can split among multiple branches.
• C. The voltage across each component is zero.
• D. The total current is the sum of the currents through each component.

Answer: (A)

In a series circuit there is only one path for the current, so the same amount of charge flows through every component in the loop. That means the current is identical at every point along the path, even though the voltage drops across individual components can differ depending on each component’s resistance. The total current isn’t the sum of currents through different parts because there aren’t multiple branches to share the current; there’s just one current value that travels through every component.
