I'm being taught electromagnetism at university, but there's one definition that has been left slightly ambiguous for an electric field to be conservative I've been taught that
1) [tex]\nabla[/tex]xE = 0
But I've also been taught that
2) [tex]\oint[/tex] E.dl = 0
But I am not sure if 1) & 2) have to be true for it to be conservitive.
OR that if 1) is true then 2) is true (and visa versa) ie, 1) [tex]\Leftrightarrow[/tex] 2)
So do i have to test for both to check the field is conservitive, or just one and say it implies the other.
