When electric field resolve into components.

  1. Apr 12, 2012 #1
    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?

    Thanks in advance!
    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[itex]\phi[/itex] z, or Rθ[itex]\phi[/itex].

    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.
