In the figure, if A & B are identical bulbs, which bulb glows brighter
- A A
- B B
- C Both with equal brightness
- D Both do not glow
Answer & Solution
Correct Answer
(A) A
Step-by-step Solution
Detailed explanation
For bulb \(\mathrm{A}, \mathrm{I}_1=\frac{\mathrm{V}_{\mathrm{o}}}{\mathrm{X}_{\mathrm{L}}}=\frac{\mathrm{V}_{\mathrm{o}}}{\mathrm{w}_{\mathrm{L}}}=\frac{\mathrm{V}_{\mathrm{o}}}{\mathrm{w} \times 100 \times 10^{-3}}=\frac{10 \mathrm{v}_0}{\mathrm{w}}\) For bulb…
