Which statement is true regarding voltage?

• A. Voltage can work independently without current.
• B. Voltage by itself does no work, it has potential to do work.
• C. Voltage is equivalent to electrical current.
• D. Voltage indicates the flow of electricity in a circuit.

Answer: (B)

The correct answer highlights that voltage, in itself, is not responsible for doing work; instead, it represents the potential to do work. In electrical systems, voltage is the driving force that pushes electric charges through a circuit, similar to how pressure pushes water through a hose. While voltage indicates the potential energy per unit charge, it requires a complete circuit and the presence of current (flow of charges) to perform any work, such as lighting a bulb or powering a device. Voltage cannot function in isolation; it needs current to translate that potential energy into actual work done. Understanding this distinction is crucial for grasping fundamental electrical concepts, such as how electrical systems are designed and operated.
