Final answer:
The maximum number of conductors in a conduit is determined by NEC standards and varies based on size and types of conductors and conduit, making 'none of the above' the correct answer. The student's secondary questions relate to advanced physics and engineering concepts such as Ampere's force law, Earth's magnetic field effects, and properties of superconductors and drawn wires.
Step-by-step explanation:
The question regarding conductor capacities within a conduit does not have sufficient context to provide a specific numerical answer, as the actual number depends on numerous factors including the conduit size, conductor size, type of wire insulation, and allowable fill according to the National Electrical Code (NEC) or other relevant standards. Typically, the range is not limited to 3, 100, or 200, but calculated based on these factors. Therefore, the most appropriate answer from the options provided is 'none of the above.'
As for the Integrated Concepts problem, the current required in the upper wire to be held above the lower wire by repulsion can be determined using Ampere's force law, and as for the question about the effects of the Earth's magnetic field, superconductors, and the effect of drawing a wire, these are advanced physics and engineering concepts that deal with electromagnetism, materials science, and electrical engineering principles.
