The resistance of hot tungsten filament is about 10 times the
An incandescent bulb has a thin filament of tungsten that is heated to high temperature by passing anelectric current. The hot filament emits black-body radiation. The filament is observed to break up atrandom locations after a sufficiently long time of operation due to non-uniform evaporation of tungstenfrom the filament.

Calculation of Resistance of Tungsten FilamentGiven:Temperature at which resistance of tungsten filament is measured, T1 = 150°CResistance of tungsten filament at T1, R1 = 133 ΩTemperature at which resistance is to be calculated, T2 = 500°CTemperature coefficient of resistance of tungsten, α = 0.0045 per °CFormula:R2 = R1 [1 + α(T2 - T1)]Solution:Substituting the given values in the ...
why tungsten is used as filament - EduRev Class 10 Question
Information about why tungsten is used as filament covers all topics & solutions for Class 10 2024 Exam. Find important definitions, questions, meanings, examples, exercises and tests below for why tungsten is used as filament .
Tungsten is used for the construction of filament in electric bulb ...
Tungsten has the highest melting point of any metal, reaching as high as 3,422 degrees Celsius (6,192 degrees Fahrenheit). When an electric current passes through the filament, it heats up and emits light. The high melting point of tungsten allows the filament to reach extremely high temperatures without melting or deforming.
