Question

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

Answer 1

Answer: (B)

$R_{A} < R_{B}$

Answer 2

In parallel $P_{consumed} \propto \text{Brightness} \propto \frac{1}{R}$

$P_{A} > P_{B}$ (given) $\therefore R_{A} < R_{B}$
