Define dielectric strength and relative permeability:

1.	Define dielectric strength and relative permeability:
Answer» Dielectric strength: The maximum value of electric field (on potential gradient) that a dielectric material can tolerate without it's electric break down and it's dielectric strength. S.I. unit of dielectric strength of a material is v/m but practical unit is mv/mm. Relative permeability: It is the degree or extent to which magnetic lines of force ca enter a substance and is denoted by μ.e.g., permeability of soft iron is 1000 time greater than that of air.

Dielectric strength: The maximum value of electric field (on potential gradient) that a dielectric material can tolerate without it's electric break down and it's dielectric strength.

S.I. unit of dielectric strength of a material is v/m but practical unit is mv/mm.

Relative permeability: It is the degree or extent to which magnetic lines of force ca enter a substance and is denoted by μ.e.g., permeability of soft iron is 1000 time greater than that of air.

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.
