Question

The electric intensity $E$, current density $j$ and specific resistance $ho$ are related to each other through the relation\

Professor PC Thomas Classes · Answer

Current density $j=\frac{I}{A}$ Electric intensity $E=\frac{V}{L}$\ We have $I=\frac{V}{R}$\ But $\mathrm{R}=\frac{ho \mathrm{L}}{\mathrm{A}} \quad 	herefore \mathrm{I}=\frac{\mathrm{VA}}{ho \mathrm{L}}$\ $\frac{\mathrm{I}}{\mathrm{A}}=\frac{\mathrm{V}}{\mathrm{L}} 	imes \frac{1}{ho} \quad$ but $j=E 	imes \frac{1}{ho}$\
