    Why does a light bulb burn out?

    Homework Statement The problem is that I cannot figure out why a filament will burn out in a particular spot. Higher resistance = lower current why does the filament heat up more? Homework Equations R2= R1[1+a(T2-T1)] Resistance = (resistivity * L)/ A R= V/I The Attempt at a...
