The adjoining figure shows two bulbs `B_(1)` and `B_(2)` resistor `R` and an inductor and `L`. When the switch `S` is turned off A. The bulb `B_(2)` lights up earlier than `B_(1)` and finally both the bulbs shine equally brightB. `B_(1)` lights up earlier and finally both the bulbs acquire equal brightnessC. `B_(2)` lights up earlier and finally `B_(1)` shines brighter than `B_(2)`D. `B_(1)` and `B_(2)` light up together with equal brightness all the time |

Answer» Correct Answer - C In L-R circuit current grows exponentially. So, `B_(2)` lights up earlier and finally `B_(1)` shines brighter than `B_(2)`. |
