Question: 1 / 1030

Static dischargers help eliminate radio interference by dissipating static electricity into the atmosphere at what levels?

High current levels

Low voltage levels

High voltage levels

Low current levels

Static dischargers are designed to dissipate static electricity from the aircraft into the atmosphere. This static electricity buildup can interfere with radio communications and navigation equipment. Since static electricity commonly presents itself at low current levels, it is important to have static dischargers that are effective at dissipating this low current static electricity to minimize radio interference. Therefore, the correct answer is "D. Low current levels."

In this question, option A (high current levels) is incorrect as static dischargers are intended to handle low current levels of static electricity. Option B (low voltage levels) and option C (high voltage levels) are also incorrect as the effectiveness of the static dischargers is more related to the current levels of static electricity rather than voltage levels.
