Assertion (A): When three electric bulbs of power 200 W, 100 W and 50 W are connected in series to a source, the power consumed by the 50 W bulb is…
Assertion (A) : When three electric bulbs of power $\displaystyle 200 \mathrm{~W}, 100 \mathrm{~W}$ and $\displaystyle 50$ W are connected in series to a source, the power consumed by the $\displaystyle 50$ W bulb is maximum.
Reason (R): In a series circuit, current is the same through each bulb, but the potential difference across each bulb is different.
Official answer
(B)
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
