Is the material inside a light bulb a conductor or resistance?
It has high resistance.
Why are high resistance materials useful in light bulbs?
The filament in a light bulb causes the light bulb to heat up and give off life.
Why might you want to use a material with high resistance?
High Resistance Opposes the flow of Electricity that results into production of Heat and Light.
What are some devices that are wired such that they have a high resistance in order to create heat?
A light bulb is the best example. The tungsten creates such a high resistance that all the accumulated heat produces light energy.
How are light bulbs made?
A light bulb is a high resistance wire surrounded by the bulb filled with an inert gas. When electric conducts through the wire, energy is lose as heat and light.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
Which property is not important when selecting a material to use as a light bulb?
High vapor pressure
Which property is not important when selecting a material to use as a light bulb filament?
High vapor pressure
Which property is not important when selecting a material use as a light bulb filament?
High vapor pressure
What gas lights a light bulb?
A standard incandescent bulb has no gas in it. Instead it's a vacuum. The reason you get light out of it is because of the Tungsten filament has a high resistance to current flow and heats up to the point that it emits light.
What is a material that conducts current?
Material with high resistance
