Условие
Estimate the amplitude of temperature variations of the spiral filament of a light bulb powered by alternating current. [29]
Note [29]
“Determine the amplitude of temperature oscillations of the coil of an incandescent lamp connected to AC circuit”, literally in the Russian text. No AC circuit is mentioned in the 2006 English version where the problem reads: “Electrical bulb. Estimate the amplitude of the change of the temperature of the filament of the electrical bulb”
