In a series circuit, current is:

In a series circuit, current is:

• A. the same everywhere
• B. varies along the circuit
• C. greatest near the source
• D. greatest near the load

Answer: (A)

Current is the rate at which electric charges flow. In a series circuit there is only one path for the current, so the same amount of charge passes any point per second. That means the current is the same everywhere along the loop, even though the voltage drop across each component can differ depending on its resistance. The total current is set by the supply and the total resistance, but once the loop is established, the same current flows through every component. If the circuit were branched (a parallel layout), the current could split and be different in different paths.
