In a series circuit, the current through each component is:

• A. The current is inversely related to resistance
• B. The current changes with each component
• C. The same current flows through all components
• D. The current is independent of voltage

Answer: (C)

In a series circuit there is only one path for current, so the same amount of charge flows past every component in that path. That means the current is identical through all components, regardless of how their individual resistances differ. The total current in the loop is set by the supply voltage and the total resistance (I = V / R_total), while the voltage drops across each component can vary with their resistance. The other ideas don’t fit because current doesn’t change from component to component in a single path, and it isn’t independent of voltage.
