In which type of circuit is voltage the same across all components?

• A. Series
• B. Parallel
• C. Complex
• D. Conventional

Answer: (B)

When considering the characteristics of different types of circuits, the parallel circuit is unique in that the voltage across all components is the same. In a parallel circuit, multiple components are connected across the same voltage source, allowing each component to receive the full voltage. This is fundamentally different from a series circuit, where the voltage is divided among the components based on their resistance or impedance.

In a parallel arrangement, regardless of the number of components or their individual resistances, each branch experiences the same voltage drop equal to the source voltage. This property is particularly important in applications where you want to ensure that each device or component operates under the same voltage conditions.

Understanding this concept is crucial for effectively working with electrical circuits, particularly in designing circuits that require reliable voltage supply to all components.
