# When electric field resolve into components.

Hi,

Whenever I check a problem to find electric intensity at a point, it shows electricity at that particular point is resolved into components. Might be my question is a dumb one.
But seriously I wana know why does it resolved into components?
What happens if we do not care about the resolved components of electric field and go ahead and find the solution?

Vinzie :)

E is a field, a vector field that has direction and magnitude. You have to have direction and direction can be separated into coordinate components. It can be xyz, r$\phi$ z, or Rθ$\phi$.

You don't have to do it that way. It's just a very convenient way of working our some problems. If you can solve a particular problem without resolving, then go ahead and do it. No worries.
