Answer: The grounding wire is bare and not insulated to ensure effective dissipation of electrical charges into the ground, preventing electrical hazards. Reasoning: The grounding wire serves as a safety measure in electrical systems. It’s designed to provide a path of least resistance for electrical current to flow into the …

Answer: Both AC and DC can be harmful, but the severity of harm depends on various factors like voltage, current, and duration of exposure. Reasoning: he harmfulness of a current depends on factors such as voltage, current intensity, and duration of exposure. Both AC (alternating current) and DC (direct current) …

Answers: Birds don’t get shocked on power lines because they do not provide a path to ground for the electrical current. The electricity flows through the wire, and as birds are not in contact with the ground or another conductor, they do not complete a circuit and, therefore, do not …

Answer: The sparking that occurs when positive and negative wires are touched is primarily due to the flow of electrical current between them. When the two wires come into contact, electrons move from the negatively charged wire to the positively charged wire, creating a spark in the process. Reasoning: Electron …
