What happens to the brightness of a bulb if the broken filament of a bulb is joined and lighted?

What happens to the brightness of a bulb if the broken filament of a bulb is joined and lighted?

Explanation: The brigthtness will be brighter, usually for a short time, until the filament fails, because of over-voltage, as the rejoined filament is shorter as the applied voltage is still the same.

What happens if the filament of the bulb is broken?

Answer: The bulb will not glow because if the filament is broken, there is no conductive path to pass on the electricity. The filament will therefore not get heated up and it will not be able to emit light.

When the broken filament of an electric bulb is joined and worked again the brightness increases what is the reason?

When the wire is rejoined, the resistance increases. Because V=IR, Voltage also increases. Therefore, the intensity of the light increases.

What happens when a filament bulb gets brighter?

So as the filament heats up the brightness increases. The increase in resistance is also happening and they all reach equilibrium when the heat radiated equals the heat dissipated.

Does a broken filament increase resistance?

First of all joining a broken filament will be difficult. Secondly it cannot withstand the current like when it’s not broken. The resistance will be lesser than before, therefore more current can flow through it, and bulb will emit more glow and temperature will also be more higher than before.

What happens to the brightness or intensity of the lamps as more and more lamps are added and connected in series Brainly?

As more bulbs are added in a series circuit, the brightness of each bulb decreases.

Will the bulb glow if filament is broken?

If the filament of the bulb is broken then the circuit would be incomplete and the bulb will not glow.

Why does the bulb not glow when the filament breaks?

General Science Because when filament is break the charge flowing through the circuit cannot transfer from one end to another.As a result bulb doesn’t glow.

When the current through an electric bulb is increased by 1\% the power is increased by?

Option (C): The power will increase by 2\%.

What affects the brightness of a bulb?

So technically speaking brightness depends on both voltage and current. An increase in either voltage or current will increase the brightness of a bulb. In incandescent bulbs, this is the case. When the brightness increases, this also means that the filament’s temperature inside an incandescent bulb also increases.

What does the brightness of the bulb indicate?

Lumens measure how much light you are getting from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light. Lumens let you buy the amount of light you want. To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens.

What happens to the resistance of the filament in a light bulb as the filament heats up?

A filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases.
