Since the two bulbs are connected in series, if the first bulb burns out there is a break in the circuit and hence the second bulb does not glow.

If there are two bulbs connected in series and one blows out, what hap...
When two bulbs are connected in series, they share the same current and the voltage is divided between them. If one bulb blows out, the circuit is broken and the current cannot flow through it anymore.

Explanation:

• In a series circuit, the current passing through each component is the same, and the voltage is divided between them according to their resistance.

• When a bulb blows out, it acts as an open circuit, meaning that the current cannot flow through it anymore.

• As a result, the other bulb in the circuit will stop glowing because there is no current flowing through it.

• The voltage across the second bulb will be zero since it is no longer connected to a source of energy.

• Therefore, the other bulb stops glowing when one bulb blows out in a series circuit.

• However, if the bulbs were connected in parallel, the other bulb would continue to glow since it would still have a source of energy and current flowing through it.

Because in series connection current has only one direction if there any problem then other also effect by that
