Figure shows two bulbs B1 and B2, resistor R and an inductor L. When the switch S is turned off, |
both B1 and B2 die out promptly
both B1 and B2 die out with some delay B1 dies out promptly but B2 with some delay B2 dies out promptly but B1 with some delay |
B1 dies out promptly but B2 with some delay |
Here the bulb B1 will die out promptly but B2 with some delay. The reason is that the branch of bulb B2 contains inductance. Due to the effect in inductance, the current in this branch continues to flow for sometime even the switch S is turned off.
