Question 417Electricity & Electronics - QMED
70% to passWhen a fluorescent lamp has reached the end of its useful life, it should be replaced immediately. If not, what condition could the resultant flashing cause?
The correct answer is D) damaging the lamps starter and ballast circuit. When a fluorescent lamp reaches the end of its useful life, the lamp's internal components, particularly the starter and ballast, can be damaged if the lamp is not replaced immediately. The lamp's flickering or flashing behavior can overload and damage the starter and ballast, potentially leading to their failure. Replacing the lamp before this occurs is important to prevent further damage to the lighting circuit. The other options are incorrect because: A) tripping the circuit breaker is not a likely outcome, B) the lamp is unlikely to explode, and C) short-circuiting adjacent circuits is not a common result of a failed fluorescent lamp.
