Electrical Power & Heating Effect

If two bulbs, whose resistances are in the ratio of $1 : 2$ are connected in series, the power dissipated in them has the ratio of

Show answer and solution

Answer: (d)

In series the current is the same, so $P = I^2 R \propto R$ .
$P_1 : P_2 = R_1 : R_2 = 1 : 2$ .
So the answer is (d) 1 : 2.
