JEE Main 2022 · 28 Jul · Shift 2, Physics question 26

An electrical bulb rated 220 V, 100 W, is connected in series with another bulb rated 220 V, 60 W. If the voltage across combination is 220 V, the power consumed by the 100 W bulb will be about ______ W.

Answer and worked solution

Official answer: 14

Resistances 484 Ω and 806.7 Ω; I=2201290.7I=\frac{220}{1290.7} A.

Power I2×484≈14I^2\times484\approx14 W.

Answer: 14
