Q. Two bulbs are working in parallel order. Bulb $A$ is brighter than bulb $B.$ If $R_{A}$ and $R_{B}$ are their resistance respectively then
A) $R_{A} > R_{B}$
B) $R_{A} < R_{B}$
C) $R_{A} = R_{B}$
D) None of these
Explanation
(b) In parallel$\ P_{consumed} \propto$ Brightness $\propto \frac{1}{R}$
$P_{A} > P_{B}\ \lbrack Given\rbrack\ \ \therefore R_{A} < R_{B}$
