Which statement correctly describes a parallel circuit?

• A. Components share the same current path
• B. Components are connected across the same two nodes
• C. There is a single path for the total current
• D. The voltages across components must be different

Answer: (B)

In a parallel circuit, each component is connected across the same two nodes, so every component experiences the same voltage from the source.

Because they share the same two nodes, the voltage across each branch is equal. The current, however, can split at the node and flow through each branch independently, so the total current is the sum of the currents through all branches. If one branch changes its resistance, its current changes while the voltage across all branches remains the same.

This is why the statement about components being connected across the same two nodes best describes a parallel connection. The other ideas describe a series setup (one path for current) or incorrectly suggest that voltages across components must differ.
