Q. Electric field and current density (J) have relation
Current Electricity
A
$E \propto J^{-1}$
19%
B
$E \propto J$
52%
C
$E \propto \frac{1}{ J ^{2}}$
13%
D
$E^{2} \propto \frac{1}{J}$
14%
Solution:
According to the relation
$\sigma E = J$, where $\propto$ is conductivity and is a constant for specific material
$E \propto \,J$
