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 instrument is used to mesure the brightness of light?
Scroll down to related links and look at "Brightness - Wikipedia" and "Light intensity - Wikipedia".
The brightness or dullness of a color?
intensity
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 unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the increase in brightness of light is called what?
It gets brighter (at least until it burns out)
Difference between lumen's and ANSI lumen's?

in foot-candles. i.e. the brightness of a candle one foot away
Why laser torch light is more than general torch light?
There is not more brightness for laser torch light. The light brightness is based on unit lumens. Lumens is more, the touch light is more lighter.
The unit light-year is a measure of A. brightness. B. distance. C. time. D. temperature?
no the correct answer is really time
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.
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
Unit used to measure the stars is called a?
magnitude for brightness, lightyear for distance, degrees C or K for temperature or colour, solar masses for mass, ...
