- DBlackout
Explanation
A blackout is a complete and prolonged loss of electrical power, making it distinct from partial or momentary power disturbances.
Common mistakes.
- A. A spike is a sudden, extremely brief overvoltage event that can damage sensitive hardware but involves excess voltage, not a loss of power.
- B. A brownout is a partial, sustained reduction in voltage below the normal operating level - power is still present but degraded, not completely absent.
- C. A surge is a temporary increase in voltage that lasts longer than a spike but still represents excess electrical energy rather than a loss of power.
Concept tested. Power disturbance terminology - blackout vs. other events
