A heating element has a resistance of 100Ω at room temperature. When it is connected to a supply of 220V a steady current of 2A passes in it and temperature is 500°C more than room temperature. What is the temperature coefficient of resistance of the heating element?
  • a)
    5 × 10–4 °C–1
  • b)
    2 × 10–4 °C–1
  • c)
    1 × 10–4 °C–1
  • d)
    0.5 × 10–4 °C–1
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A heating element has a resistance of 100Ω at room temperature. ...
Resistance after temperature increases by 500°C = 220/2 = 110Ω
110 = 100 (1 + α500) 

a = 2 × 10-4 °C-1
