exploding light bulb issue

[Glenn McCrorey]

So a renter said a light bulb in a chandelier exploded and caught on fire (I'm sure this is an exaggeration) so I did some research on the internet and sent her an email saying it's no big deal with the following explanation which I think cleared it up pretty well:

The reason is simple. Just before they burn out, incandescent bulbs get a surge of current as the tungsten filament loses its resistance just prior to burning away. That surge raises the energy going across the filament as E = IV > iV = e where I > i is the surge in current, V is the voltage across the filament. So E > e and that surge in energy converts immediately into heat energy E = Q which stresses the glass in the bulb so it pops.
