Electrical Safety - GCSE Physics

🦊 In this GCSE Physics video, we explain the different potential voltages of the three wires in a cable: the live wire at 230 volts, the neutral wire at approximately 0 volts, and the earth wire also at 0 volts to ensure safe operation. The live wire is the most dangerous due to its high potential difference, which can still pose a risk even when an appliance is switched off, allowing current to flow through a person to the earth if touched. Additionally, the video highlights the importance of a fuse connected to the live wire, which breaks the circuit if the current becomes too high, enhancing safety in electrical systems.
