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→
where r – Resistivity
J→– current density
∣J→A∣>∣J→B∣
\ EA > EB
