Explain the power rating of a bulb, say 60W, what if the
voltage changes
Answer Posted / abishekmittal
Answer 1. is correct. In addition to it, with the decrease
of voltage, current will also come down (V is directly
proportional to I for constant R). Hence the bulb will get
dimmed as the I^2R also gets reduced
