If two bulbs are connected in parallel and one bulb blows out, what happens to the other bulb?

When two bulbs are connected in parallel, each bulb is connected directly to the voltage source. This arrangement means that each bulb operates independently of the other. If one bulb blows out, the circuit through that bulb is interrupted, but the circuit for the other bulb remains intact.

Here's what happens in detail:

1. Independent Circuits: In a parallel connection, each bulb has its own path for current. Therefore, the failure of one bulb does not affect the performance of the other.

2. Voltage Supply: The voltage across both bulbs remains the same as long as the power supply is functioning. So, when one bulb blows out, the other bulb continues to receive the full voltage.

3. Current Flow: The current through the remaining operational bulb will not change due to the failure of the other bulb, allowing it to continue functioning normally.

In summary, if one bulb blows out in a parallel circuit, the other bulb continues to work without any change in its operation. This is a significant advantage of using parallel connections for lighting.
