By increasing the temperature, the specific resistance of a conductor

1.	By increasing the temperature, the specific resistance of a conductor and a semiconductor- (i) increases for both. (ii) decreases for both. (iii) increases for a conductor and decreases for a semiconductor. (iv) decreases for a conductor and increases for a semiconductor.
Answer» Answer is (iii) increases for a conductor and decreases for a semiconductor. Specific resistance of a conductor increases and for a semiconductor decreases with increase in temperature because for a conductor, a temperature. coefficient of resistivity α = + ve and for a semiconductor, α = -ve

Answer»

Answer is (iii) increases for a conductor and decreases for a semiconductor.

Specific resistance of a conductor increases and for a semiconductor decreases with increase in temperature because for a conductor, a temperature.

coefficient of resistivity α = + ve

and for a semiconductor, α = -ve

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
