Static discharges help minimize interference by dissipating static electricity into the atmosphere at low current levels. Which option lists a low current level as the correct characteristic?

Static discharges help minimize interference by dissipating static electricity into the atmosphere at low current levels. Which option lists a low current level as the correct characteristic?

• A. High current levels
• B. Medium current levels
• C. No current
• D. Low current levels

Answer: (D)

The key idea is that dissipating static electricity into the atmosphere should release energy very quietly, so it doesn’t disturb sensitive systems. A low current discharge does exactly that: it allows the built-up charge to dissipate with only a tiny, brief surge, producing minimal electromagnetic interference with communication, navigation, or warning equipment. Higher currents would create bigger sparks and more EMI, potentially causing noise or interference, while no current would mean the charge remains and might cause unpredictable effects later. A discharge described as low current levels is therefore the best fit for minimizing interference.
