Two electric bulbs rated P1 and watt at V volt are connected in series across V volt mains, then their total power consumption P is(P1+P2)√P1P2P1+P22P1P2P1+P2

Two electric bulbs rated $P_{1}$ and watt at $V$ volt are connected in series across $V$ volt mains, then their total power consumption $P$ is
$(P_{1} + P_{2})$
$\sqrt{P_{1} P_{2}}$
$\frac{P_{1} + P_{2}}{2}$
$\frac{P_{1} P_{2}}{P_{1} + P_{2}}$
