AI Thread Summary
The discussion addresses two main questions: the power consumption of light bulbs and the invention of the lightning conductor. Light bulbs can vary widely in wattage, with compact fluorescent bulbs typically consuming 10-20 watts and incandescent bulbs ranging from 40 to 100 watts. The power rating of a lamp depends on its resistance and the voltage applied. For the invention of the lightning conductor, it is noted that Benjamin Franklin created it in 1752, while Thomas Edison is mentioned in relation to electric lighting. Overall, the power of a light bulb can be determined by checking its wattage rating.

Your first question is very poorly worded. What exactly do you mean? If you mean an electric light, look at the bulb and it will tell you. My lamp at the side of me now is 60W ie 0.060kW.

regards lightning conductor - do a search on Google.
 
Lamps can have just about any power ratings -- the power dissipated by the lamp depends upon its resistance and the voltage applied to it. Flashlight bulbs and search lights are very different in their power ratings.

Compact flourescent light bulbs generally consume about 10-20W at about 5x the efficiency of an incadescent. Regular incadescents come in 40-100w versions. Though like chroot said, light bulbs come in all sizes - down to a few miliwatts and up to a few thousand watts.

For the second part, do a google search for Thomas Edison.
 
Ben Franklin invented the Lightning Rod, or Lightning Conductor in 1752.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
