In a circuit that is fitted with a bulb which is the factor that affects brightness of that bulb: current in the circuit or the voltage offered by the battery in that circuit?

 

The Enable adaptive brightness setting under Display in Power Options allows users to turn on or off having Windows monitor ambient light sensors to detect changes in ambient light and automatically adjust the display brightness as needed to match surrounding lighting conditions.

 

My question is: is power directly proportional to brightness? The question definitely seems to assume so but where does this relationship break down and when is it a fair assumption?

 

How to Add or Remove "Dimmed display brightness" from Power Options in Windows The Dimmed display brightness setting in Power Options allows users to specify the brightness level in percentage for when your display is dimmmed after the dim display after idle timeout has been reached. This setting applies only to portable computers (ex: laptop or tablet) that support Windows control of the ...

 

Recently I learned that apparently both radiance and luminance are independent of the distance between the light emitting object and the observer. The reasoning was that although the radiant/lumni...

 

High performance - Maximizes screen brightness and might increase PC performance. This plan uses a lot more energy so your laptop battery won't last as long between charges. Ultimate Performance - Only available starting with Windows 10 build 17083. Provides ultimate performance on higher end PCs.

 

Brightness of lamp (power) depends on two factors: Current which flows through the lamp. voltage (p.d) across the lamp. In the figure: When the variable resistance increases what happens to the

 

Assume that there is an ideal voltage source and the resistance of each bulb is the same. I believe that the brightness/power remains the same because the voltage across each bulb is constant and the current across each bulb is therefore constant. I don't see how adding more bulbs could change this.

 

How to Enable or Disable Adaptive Brightness in Windows 10 Displays (especially on laptops and tablets) may utilize ambient light sensors to detect surrounding levels of light. The adaptive brightness feature in Windows monitors ambient light sensors to detect changes in ambient light and automatically adjust the display brightness as needed to match surrounding lighting conditions. While ...

 

How to Adjust Screen Brightness in Windows 10 Information If you have a laptop or tablet you might need to occasionally change the scree
