The size of a filament affects its glow by influencing the resistance of the material to the flow of electricity. A larger filament typically has higher resistance, causing it to heat up more and emit a brighter glow compared to a smaller filament under the same electrical current. Additionally, the size can impact the surface area available for heat dissipation, affecting the temperature and brightness of the glow.
What else can I help you with?
What heats the filament?
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Does size of a glow stick effect how long it glows?
The size of a glow stick does not necessarily affect how long it glows. The glow duration is primarily determined by the chemicals inside the glow stick and their reaction rate. However, larger glow sticks may have more chemicals, which could potentially result in a longer glow time.
Why does a light bulb filament glow?
A light bulb filament glows when electricity passes through it, causing the filament to heat up and emit light due to incandescence. The high temperature of the filament makes it glow and produce visible light.
How does bulb glow?
When electricity flows through the filament of a light bulb, it heats up the filament to such a high temperature that it begins to glow and emit light. This process is known as incandescence. As the filament glows, it emits light in the visible spectrum, allowing us to see.
What does a filament lamp do in a circuit?
A filament lamp produces light by converting electrical energy into heat and then light. It acts as a resistive load in the circuit, meaning it resists the flow of current and causes the filament to glow and produce light.
Why does the filament of a lightbulb glow while the connecting wires do not?
they glow
What type of light glow when the filament get hot?
incandescent lights
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
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.
What heats the filament?
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Does size of a glow stick effect how long it glows?
The size of a glow stick does not necessarily affect how long it glows. The glow duration is primarily determined by the chemicals inside the glow stick and their reaction rate. However, larger glow sticks may have more chemicals, which could potentially result in a longer glow time.
Why does a light bulb filament glow?
A light bulb filament glows when electricity passes through it, causing the filament to heat up and emit light due to incandescence. The high temperature of the filament makes it glow and produce visible light.
How does the light in a resistor glow?
The light glows because of the hot Filament.
Property of the filament that makes it light up when electricity flows through it?
Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
Why is gas in a light bulb?
Mainly to prevent the filament, the glow wire from burning up.
Does the filament of an incandescent light bulb glow because it gets extremely hot?
yes
