Question 116Electricity/Electronics - Assistant Engineer70% to pass
Four lamps are connected in parallel in a single circuit. If one of the lamps burns out, what will happen to the other lamps?
AI Explanation
The correct answer is C) the remaining lamps will burn with their original intensities.
This is because when multiple lamps are connected in parallel, the failure of one lamp does not affect the others. In a parallel circuit, each lamp has its own path for the electrical current, so if one lamp burns out, the current will simply bypass that lamp and continue to flow through the other lamps, maintaining their original brightness.
The other answer choices are incorrect because: A) the other lamps will not go out, B) they will not become dimmer, and D) they will not become brighter. The parallel circuit design ensures the remaining lamps continue operating normally when one lamp fails.
