Final answer:
A grounded conductor must not be attached in a way that reverses its designated polarity, as it is critical to maintain the correct polarity for safety and functionality. Grounding helps fix conductors at zero volts, and it's important to not assume voltage uniformity throughout a wire in a circuit.
Step-by-step explanation:
It is not acceptable for a grounded conductor to be attached so as to reverse its designated polarity; this is false. Conductors must be connected according to their designated polarity to ensure the safety and proper functioning of electrical systems.
Additional Relevant Information:
- Grounding is the process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor.
- In a circuit diagram, the voltage is not necessarily the same at every point in a given wire; this statement is false.
- Charging an object by polarization does not require touching it with an object carrying excess charge, making the statement false.
- If a bar magnet is dropped through a copper tube, it indeed induces an electric current in the tube, so this statement is true.
