Final answer:
High-voltage wires are not wrapped in insulating material; they are held aloft by insulators. Wood can conduct a lightning strike due to dielectric breakdown. Dielectric materials reduce the electric field in capacitors, and wave-particle duality does not apply to macroscopic objects.
Step-by-step explanation:
The student has asked about an LIM's ability to protect against microshock, which relates to safety measures in electrical environments. Below, I will address True or False statements regarding electricity, which will help in understanding concepts around electrical safety and behavior.
The statement regarding high-voltage wires being insulated is false. High-voltage wires that are connected to tall metal-frame towers are indeed held aloft by insulating connectors. However, the wires themselves are not usually wrapped in insulating material due to the cost, weight, and heat dissipation considerations. Instead, they are kept at a distance from each other and from the ground to prevent unwanted electrical discharge.
It is true that lightning can travel through a tree to reach Earth. Although wood is an insulator at low voltages, the extremely high voltage of a lightning strike can cause dielectric breakdown of wood, causing it to become a conductor and allowing the lightning to pass through.
It is true that inserting a dielectric material between the plates of an air-filled capacitor reduces the electric field. This is because the dielectric increases the capacitor's capacity to store charge without increasing the voltage across its plates.
The concept that wave-particle duality exists for objects on the macroscopic scale is false. Wave-particle duality is significant at the quantum level for particles like electrons and photons, but it is not a noticeable phenomenon for large scale objects in the everyday world.
