why can't electric field lines form a closed loop?

Electric field lines form closed loops aroud a time-varying magnetic field

if itforms a closed loop then the work done to move a test charge in tht loop wont be 0 and hence it is no more conservative

thats because the electric field lines indicate the direction of the electric field so if it does form a loop then at a point it wil have 2 direction for the sam,e electri field- which isnt correctso electric field lines donot form loops

It can form provided negative and positive electric charges coexist.

 

Since isolated negative and positive electric charges d exist in nature thus electric lines of force do not always form closed loop unlike magnetic lines (as N and S poles do not occur in isolation)

static electric field lines cannot form closed loops, because potential always decreases in the direction of the field and its field energy is consumed by the body. if everything was in a steady state, then when the body reaches the same point; it should have the same potential after loosing PE continuoslu. is it possible? however it is not so in dynamic fields!!

 

i am new here and am looking for some ratings to boost up!! if you liked my answer pls......    ....... thank you
