Final answer:
The electrical power panel is typically on the overhead panel and ADG controls on the center pedestal, making the answer (d) Both a and c. The electric field strength between two parallel metal plates is the same at all points.
Step-by-step explanation:
The location of the electrical power panel and Auxiliary Drive Generator (ADG) controls can vary depending on the aircraft design, but typically, the electrical power panel is located on the overhead panel (a), while the ADG controls can be found on the center pedestal (c). Therefore, the answer would be (d) Both a and c. As for the electric field created by two parallel metal plates, the strength of the electric field is uniform between the plates and thus the electric field would be the same at all points (d). This is because the electric field lines between two parallel plates are equally spaced and parallel to each other, indicating a uniform field.
