Please give step by step solution so I can understand and follow along. I will rate, thank you. 3. A tungsten light bulb filament (see the figure at the right) is a coil of a coil to reduce evapor...
3. A tungsten light bulb filament (see the figure at the right) is a coil of a coil to reduce evaporative losses (the light bulb itself contains an inert gas to also reduce evaporative losses and to also reduce the operating temperature of the filament. The inert gas is usually argon). The uncoiled diameter of the filament is 47 μm and the density of tungsten is 19.25 g/cm3. If a 120 V potential difference were maintained over the filament what length is required for a power of 60 W at 2500° c (the resistivity of tungsten is 5.45 x 108 2-m at 20°C and α 0.0045 °C)?
