If two equal coil A and B are parallel and you supply them at the same time which one will be closed at the first time?
If both coils are perfectly identical , they should close at same time. But in practice, it is not possible to have perfectly identical coils. Even though2 colis are of same model , same manufacturer, they will have slight difference in their mechanical mechanism, slight difference in their electrical properties and hence their operating time will slightly differ, may be my some fraction of seconds.
