How is voltage applied in each branch of a parallel circuit?

• A. Unequally
• B. Randomly
• C. Equally
• D. According to resistance

Answer: (C)

In a parallel circuit, the key characteristic is that each branch receives the same voltage. This is due to the nature of parallel connections, where each component or branch is connected directly across the power source. Therefore, no matter how many branches are present or what their individual resistances are, the voltage applied to each branch remains constant and equal to the source voltage. This uniform application of voltage allows each branch to operate independently; for instance, if one branch fails or is disconnected, it does not affect the voltage experienced by the other branches. As a result, devices connected in parallel can function properly even if others are turned off or malfunctioning. The other choices do not accurately describe the behavior of voltage in parallel circuits: applying voltage unequally, randomly, or according to resistance would contradict the fundamental principles of how parallel circuits are designed and function.
