Which of the following defines the term "Voltage"?

• A. Flow of electrical charge
• B. Potential difference
• C. Electrical work done
• D. Rate of electrical flow

Answer: (B)

Voltage is defined as the potential difference between two points in an electrical circuit. It measures the energy per unit charge that is available to move electrons through a conductor. Essentially, voltage indicates how much energy is provided to push the electrical charges through the circuit, enabling electrical devices to operate. This potential difference is critical for the movement of electrons, as it determines the current flow in the circuit. When you connect a power source to a load, the voltage difference is what causes the current to flow, allowing work to be done, which includes powering devices. In contrast, the other answers refer to different concepts related to electricity. The flow of electrical charge corresponds to current, while electrical work done relates to energy consumed, and the rate of electrical flow could be interpreted as current flow as well. Understanding voltage as the potential difference helps clarify its role in electrical systems and circuits.
