Four lamps are connected in series in a single circuit. If one of the lamps burns out, what will happen to the other lamps?

Aall go out
Bbecome dimmer
Cburn with their original intensities
Dbecome brighter
AI Explanation

The correct answer is A) all the lamps go out. When lamps are connected in series, they share the same current. If one lamp burns out, it creates an open circuit, causing the current to stop flowing through the entire series. As a result, all the other lamps in the series will also go out because they no longer have power supplied to them. The other options are incorrect because in a series circuit, if one lamp fails, the current is interrupted, and the remaining lamps cannot continue to operate at their original or a brighter intensity.
