How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
Does a light bulb have vacuum in it?
Yes, the inside of a light bulb is vaccum sealed to increase the lifespan and brightness of the bulb. If there was air in there, the filiment would burn up and not last very long. This was an important discovery made by Thomas Edison when he invented the light bulb.
Describe how a meter would be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
What if the light bulb wasn't invented?
Then there would be no light bulb. We would have to watch TV by candle light.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
What object could you use to measure the brightness of the bulb?
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
How did you determine if there had been a change in the brightness of the bulb?
You would have to measure the lumen output before and after to determine is there was a change. There are light meters that can do this. You need to be aware of any background or ambient light during such measurements.
What are some information on light bulb?
brightness
If the electrical conductivity in an electrical circuit decreases then the brightness of the light bulb does what?
Then the brightness of the light buld increases.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
Does a 9 volt battery light a light bulb?
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
What SI measurement measures the brightness of a light bulb?
lumen
Does a light bulb have vacuum in it?
Yes, the inside of a light bulb is vaccum sealed to increase the lifespan and brightness of the bulb. If there was air in there, the filiment would burn up and not last very long. This was an important discovery made by Thomas Edison when he invented the light bulb.
How does area of the circuit affect brightness of bulb?
if light is low it can cuase the bulb brightnees.
How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
