In parallel, what is shared between components?

• A. Voltage
• B. Power
• C. Current
• D. Resistance

Answer: (C)

In parallel circuits, the same voltage is across every component. This happens because each component is connected directly across the same two nodes from the source, so the potential difference seen by each one is identical. Currents do not stay the same across branches; they split. The current through each branch is I = V/R_branch, so branches with lower resistance draw more current while the voltage stays the same for all. The total current from the source is the sum of the branch currents. Resistance can differ from branch to branch, and power dissipation is different in each branch based on its own current and resistance. So the consistent quantity shared by all components in parallel is voltage.
