The V-Igraph is given for two conductors of same area and length. If sigma_(1)and sigma_(2) are the cnductivities of the conductors 1 and 2 respectively, (sigma_(1))/(sigma_(2))=

Answer»

`2:1`
`3:1`
`1:SQRT2`
`1:3`

Solution :`sigmaprop1/R"When l and A=same"`
`Rprop tan theta,sigmaprop(1)/(tan theta)`
`(sigma_(1))/(sigma_(2))=(TAN30^(@))/(TAN60^(@))=1/3`
