Aluminium
Paper
Rubber
Mica
Answer is Wrong!
Answer is Right!
The correct answer is: Aluminium.
Aluminium has a positive temperature coefficient, which means that its resistance increases with increasing temperature. This is because the resistance of a conductor is inversely proportional to its resistivity, and the resistivity of aluminium increases with increasing temperature.
Paper, rubber, and mica all have negative temperature coefficients, which means that their resistance decreases with increasing temperature. This is because the resistance
