The brightness of a lightbulb is given by its power.
P = I2R, and so brightness depends on current and resistance.
If the bulbs are identical, they have the same resistance.
They may not, however, experience the same current.
What factors affect brightness?
The brightness of light can be affected by several factors, including the distance between the light source and the object, the intensity of the light source, and the presence of any objects that absorb or scatter the light.
What 3 things affect apparent brightness?
Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object.
An object's apparent magnitude depends on its intrinsic luminosity, its distance, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer.
What are the factors of brightness?
Factors Affecting Object Luminosity
There are two important variables: the object's effective temperature and size, and its radius, R, which affects the object's luminosity.
Size and Effective Temperature: Astronomers examine a star's size and effective temperature to calculate its brightness.
