What is the voltage throughout a parallel circuit?

• A. Different across each branch
• B. Zero on all branches
• C. The same across all branches
• D. Variable at each branch

Answer: (C)

In a parallel circuit, the voltage across each branch is the same. This is a fundamental principle of parallel circuits; regardless of the number of components connected in parallel, they all experience the same electrical potential difference. When a voltage source is connected to the parallel branches, each branch receives the full voltage of that source. This characteristic is crucial for functioning devices because it ensures that each component operates under the same voltage level, allowing them to work effectively. In contrast, the notion that there could be different voltages across branches or that the voltage could be variable would imply an inconsistency in the electrical potential, which is not how parallel circuits operate. Each branch can have different resistances or currents, but the voltage remains constant across all.
