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
What is the connection between the reading and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.
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 is the connection between the reading and brightness of the bulb?
The reading is much easier when you sit under the brighter bulb.
What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.
What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.
How do you alter the brightness of a bulb?
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
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.
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 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
Is shape affects the brightness of the stars?
no
What affects the brightness of stars?
relative "brightness" is based on distance, size, and temperature
How thickness of wire affects brightness of bulb?
Considering that everything else is equal, ie. glass, incoming wire. If you are talking only about the filament wire that is attached between the Two poles inside the bulb, the answer is friction. The thicker the wire the less resistance it will have and will allow more electricity to pass without creating friction, the friction is what causes the wire to heat up and glow.
What are some information on light bulb?
brightness
What is the connection between the reading and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.
How do we decrease the brightness of a bulb?
If the bulb is of the incandescent variety, then reducing the current in the circuit will do this.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
