In a parallel circuit, the voltage drop across each component is the same. Which statement best describes this behavior?

• A. Ohm's Law
• B. Law for voltage in Parallel circuit
• C. Law for current in a series circuit
• D. Law for resistance in a parallel circuit

Answer: (B)

In a parallel circuit, all components are connected across the same two points, so they share the same potential difference as the source. This means the voltage drop across each branch is identical, equal to the supply voltage. That behavior is described by the law for voltage in a parallel circuit. Ohm's Law describes V = IR for a single element and doesn’t specify how voltage is distributed across parallel branches. The current in a series circuit is the same through every component, which is a different property, not about parallel voltage equality. The idea of a specific “resistance law in a parallel circuit” isn’t the rule governing the equal voltage across branches. Thus, the best description is the law for voltage in a parallel circuit.
