Multiple Choice

In a series circuit, current is ______ at any point in the circuit.

In a single-path circuit, the current is the same everywhere along the loop. There’s only one route for charges to flow, so the same amount of charge per second passes through every component. The current value is set by the applied voltage and the total resistance: I = V / R_total. While the current stays constant, the voltage drop across each component can differ (V = I·R for each element) depending on its resistance. If there were branching paths, currents could split and differ in branches, but in a series circuit there’s no branching, so the current remains constant at any point.
