A resistance of fruotum shape is shown in figure. If a current i passes through the resistance, the electric field at A and B are related as –

A

EA> EB

B

EB> EA

C

EA = EB

D

There is no relation

Answer

EA> EB

Explanation

Solution

E=ρJ\overset{\rightarrow}{E} = \rho\overset{\rightarrow}{J}

where r – Resistivity

J\overset{\rightarrow}{J}– current density

JA>JB|{\overset{\rightarrow}{J}}_{A}| > |{\overset{\rightarrow}{J}}_{B}|

\ EA > EB
