Since the bulb has a constant resistance, increasing the voltage will increase the current which will increase the brightness until the bulb blows in a flash of light.
Ohm's Law governs this process where Volts = Current x Resistance.
Another Answer Incandescent lamps do not have a constant resistance, as their resistance increases significantly with temperature. In fact, the 'hot resistance' of a lamp filament is around 10-18 times higher than its 'cold resistance'. The temperature increase, of course, is due to the current passing through the filament. This means incandescent lamps do notobey Ohm's Law and are, thus described as being 'non-ohmic' or 'non-linear'. However, to answer your question directly, the rated power of a lamp only occurs at the lamp's ratedvoltage. Even a small reduction in voltage will result in a significant loss of power and, thus, brightness. So, in this sense, a lamp's brightness is determined by the voltage applied across its filament.

What happens if a large current is forced through a high resistance wire?
A large amount of energy, calculated as the voltage difference across the wire, will be expended in that section of wire. This would most likely cause it to glow and/or create a lot of heat, which could possibly melt the wire and break the circuit (this is the principle any fuse is based on - a fuse is a low resistance wire that has a low melting temperature, so a "large" current will cause the fuse to heat excessively, melting the conductor). A light bulb is exactly this - a "high resistance" wire (or filament), where relatively large current is pushed through a very small cross section of wire, causing it to glow.
What are some of the important elements of an electronic circuit?
there is mainly zarton and eracitiom in electronics because they are the elements that give an object its natural glow
What happens when a bulb gets fused?
When a bulb fuses the circuit is broken if it is on a serial circuit. If the bulb is on a parallel circuit, only the fused bulb will go out, any other bulb would remain lit. On a serial circuit, until the bulb is replaced by a new one, the circuit is not able to be used.
How does glow water glow with high lighter ink?
Glow water glows when exposed to black light or UV light due to the presence of fluorescent compounds in highlighter ink. These compounds absorb the UV light and re-emit it as visible light, creating a glowing effect. When mixed with water, the highlighter ink disperses, allowing the fluorescent particles to illuminate the water under the right lighting conditions. The brightness and color of the glow depend on the type of highlighter used.
What is the example of glow?
glow food are those that are healthy for skin and hair.all fruits and vegetables are in the group of glow foods
What did you do to make light bulbs glow brighter?
To make light bulbs glow brighter, you can increase the voltage supply to the bulb. This will cause more current to flow through the filament, resulting in a brighter glow. Be cautious not to exceed the recommended voltage rating of the bulb, as this can lead to overheating and damage.
Connected in series or parallel will each bulb glow brighter?
In parallel, each bulb will have full voltage applied across them. However, in series, the voltage across each bulb won't be the same as supply voltage. Thereby, bulbs connected in parallel will glow brighter.
How much voltage a 0v bulb need to glow?
Some small voltage above 0.
Does glowing of bulb depends upon frequency?
No, the glowing of a light bulb does not depend on frequency. Light bulbs glow because of the electrical current passing through the filament, causing it to heat up and emit light. The frequency of the electricity supplied to the bulb affects its brightness but not whether it will glow or not.
What will happen when a 15v current flows through a 6V bulb?
It will glow VERY BRIGHTLY for a few seconds - and then burn out.
Will bulb glow in milk?
No, a light bulb will not glow if placed in milk. Milk is not a conductor of electricity, so it will not allow the flow of current needed to power the light bulb.
Why we called zero bulb to zero volt bulb?
the zero bulb required less amount of electricty to glow the voltage of bulb is below 5 volt
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
Does a large current in a circuit make a bulb bright or dim?
The glow of the bulb is due to heating of the filament to the incandescent level. Joule's heating effect gives the formula H = I2 R t. Hence more the current then more the heat and so more brightness. Thus large current makes the bulb brighter no doubt. At the same time if current exceeds the nominal level then filament would get melted and get fused.
When the 60watt bulb can glow in 30volt and 2ampere will the same bulb glow on 15volt and 4 ampere?
In a typical residential 60 Watt incandescent bulb, the resistance of the filament is what dictates the current flow given a household voltage of 120 VAC the current is 1/2 amp. By Ohm's Law that means the resistance is 240 Ohms. In your example, a 60 Watt bulb at 30 Volts drawing 2 Amps would have a resistance of 15 Ohms. If you change the voltage to 15 Volts the resistance will still be 15 Ohms and current will be V/R = 1 Amp. The bulb, if it lit at all would be less than 1/2 as bright as the 30 Volt situation.
What will happen if this 4.5 v bulb is connected to a 1.5 v cell?
The bulb need the correct voltage to operate. Your bulb would light if it is a 1.5 volt light. So the voltage of the supply and the light must be matched. Too little voltage won't light the light, too much will light it too much and blow it up.
What happens when a battery light the light bulb?
When a battery is connected to a light bulb, the electrical current flows from the battery through the wire, causing the filament in the light bulb to heat up and emit light. The battery acts as a power source, providing the necessary voltage and current to illuminate the bulb.
