Question

your company provides testing services that help customers identify and resolve performance issues with their software and e-commerce sites before they go live. to perform accurate testing, a large number of computers are required, sometimes numbering in the hundreds. recently, you have noticed that the lights in the testing lab seem dimmer than normal and sometimes flicker. which of the following electrical terms best describes the condition you are most likely experiencing?
○ power spike
○ blackout
○ brownout
○ power surge

Explanation:

To solve this, we analyze each option:

• Power spike/Power surge: These are sudden increases in voltage, often causing devices to malfunction or be damaged, not dimming lights.
• Blackout: A complete loss of power, so lights would be off, not dim or flickering.
• Brownout: A reduction in voltage in the electrical supply, which causes lights to dim and can lead to flickering as the voltage is insufficient for normal operation, matching the described condition.

Answer:

C. Brownout
