Topic: Resistivity, conductivity and temperature dependence of resistance· Current Electricity

As the temperature increases, the electrical resistance :

1. decreases for conductors but increases for semiconductors

2. increases for both conductors and semiconductors

3. decreases for both conductors and semiconductors

Best answer

Answer: 4. increases for conductors but decreases for semiconductors

Resistance of a conductor rises with temperature, while that of a semiconductor falls.

  • Conductors: more lattice vibration means more collisions, so relaxation time drops and \(R\) increases.
  • Semiconductors: heating frees more charge carriers, so \(R\) decreases.

Option (4) is correct.
