What increases when in series?

• A. Amps
• B. Power
• C. Volts
• D. Resistance

Answer: (C)

In a series arrangement of voltage sources, the voltages add up to give a higher total potential difference. The current has to flow through each element in turn, so the same current passes through every part, but the overall voltage across the entire series chain increases as you stack more sources. For example, two 9 V sources in series produce 18 V across the pair. Keep in mind the current is not increased by stacking in series; it’s the voltage that adds. If you instead consider resistors in series, the total resistance increases, which would reduce current for a fixed supply.
