current in XY

VITEEE Preparation › Electricity and magnetism questions › current in XY

the conductor XY has negligible resistance.

a) current will flow thru XY if Îµ1/R1 â‰ Îµ2/R2

B) current will flow thru XY if Îµ1=Îµ2

C) current will never flow thru XY .

d) current will always flow watever be the condition.

do ans with reason .

well c wil the ans current will never flow

reason assume current i flows from x to y so same current i will come back frm y to x hence net curent by superposition is 0.

I coming out of any 1 cell has to enter it as well....so complete paths are individual circuits....so nocurrent thru x y

C)
Current will never flow.

Since using theorem of superposition there will be no current flowing thro

reason for c is dat currents will b confined to d two loops .......n they will b loop currents ..........

aisa q iit mein poocha gaya hai
