5 bulbs are connected in series in a room. One bulb is fused. It is removed and remaining 4 bulbs are again connected in series to the same circuit. What will be the effect on the following physical quantities? (Increases, Decreases, Remain Same)
Intensity of light
Topic: Current and brightness in a series circuit
Question wording verified against source paper
Answer
Exam answer
Increases.
Explanation
At the same supply voltage, the reduced total resistance increases current, so each remaining bulb glows brighter.
