When a 40 watt lamp is connected in series with a 100 watt lamp across a 210 volt supply, which one glows brighter?

View answer and explanation

Correct option: B

40 watt lamp

Option B (40 watt lamp) is correct because in a series circuit, the lamp with higher resistance (lower power rating) glows brighter due to higher power dissipation.
