because there is a correlation between resistance and voltage and current.
The equation resistance = voltage divided by current shows that the higher the voltage, the bigger the resistance,, and the bigger the resistance the hotter the filament lamp will get because of the electrons bumping into each other which means there is a loss of energy and that energy is being transferred to the filament making the actual filament bulb hot since there is more thermal energy wasted at the end.
What else can I help you with?
What is something created when filament that becomes so hot it glows?
A light bulb is created when a filament becomes so hot that it glows. The high temperature causes the metal filament to emit light, which produces illumination in the bulb.
I need to draw a circuit diagram to show this but I have no idea how do you find the resistance of a lamp in a circuit?
If you have a lamp, you can assume that the resistance of the lamp when it is under power will follow the ohms law. BUT, one thing you must remember is, when a lamp is under load, it is glowing HOT. When metal is HOT, the molculoes of the meals are in much more active state. When this happens, the resistance will increase. Conversely, when the lamp is NOT on ON state, the filaments are cold. Moleculoes in the filaments are not as active. Thus, the resistance is lower. There is almost 10 to 1 difference in resistance from hot to cold. Taking out a multimeter and measuring the resistance of the lamp will not help you determine the resistance of the lamp when it is actually under load (with voltage applied) Really, the only thing you can do is to measure the voltage, measure the current, then arrive at the resistance mathmatically.
Why is argon used in lamp?
The traditional bulb contains a thin wire(AKA filament) that gives off light(and heat) when it's heated white hot by a current passing through it. If you were to do this in ordinary atmosphere the filament would simply burn off. But if you put the filament either in vacuum or in a non-reactive atmosphere it can glow w/o burning.
What happens when electricity flows through the filament in a light bulb?
When electricity flows through the filament in a light bulb, the filament becomes very hot and starts to emit light due to the process of incandescence. The electricity heats up the filament to a high temperature, causing it to glow and produce light.
Why does the filament become hot?
The filament becomes hot when electricity passes through it, due to resistance in the wire. This resistance causes the filament to heat up and emit light in an incandescent bulb.
WhY does a filament lamp get when you us high voltage?
because there is a correlation between resistance and voltage and current.

How does the electric lamp function using electricity?
An electric lamp works by passing an electric current through a filament inside the bulb, which heats up and produces light as a result of its high temperature. The filament is typically made of tungsten due to its high melting point. The light emitted is a result of the filament glowing white-hot when electricity flows through it.
What type of light build glows when a filament inside it gets hot?
Electric lamps having incandescent filaments.
When the filament in an incandescent lamp gets hot what kind off radiation does it give off?
the lamp gets hot
Is the resistance lower if you have a high current?
Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.
Why is a halogen lamp hot?
A halogen lamp produces light by passing electricity through a tungsten filament enclosed in a bulb containing halogen gas. This process generates a significant amount of heat due to the high operating temperature needed to sustain the halogen cycle, where tungsten evaporates and is redeposited on the filament.
Why do lamp filaments age?
The high temperature causes a small amount of the metal in the filament to evaporate away. Over some time, the filament will develop a "hot spot" where it is thinner than the rest of the filament, which causes more rapid degradation and the filement will "blow".
If a incandescent lamp is connected to a 12-v lantern battery if the current flow is 8.5mA how much?
How much what? Power? 102mW (0.102W). How much light? A filament bulb produces 1 to 3 percent of the power input as light if the proper voltage is applied. If the lamp is rated for a higher voltage, it won't get hot enough and the light out will be a lot less.
When did High Voltage Hot Rod Show happen?
High Voltage Hot Rod Show happened in 2009.
Does the glow of bulb depend on current or voltage?
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.
When was High Voltage Hot Rod Show created?
High Voltage Hot Rod Show was created on 2009-01-19.
How does electric lamp function using electricity?
You plug it in and it lights up. Current flowing in the filament makes it white hot, and it emits light.
