Homework Help: Electric Fields

  1. Mar 7, 2008 #1
    I am a little confused with an electric field, Is it the kinda force between two particles positive and negative, or the force between two like charges??? Then why is it that a positive charged particle can determine the direction of the field?????? i am a bit confused

    thankyou

    Well an electric field is defined as any region in which a charged body experiences an electric force. Convention. The convention that physicists use is that they use a +ve test charge to determine the direction of an electric field.

    [Electric field strength is given by E=F/Q]
