Visual representation of electric fields. They originate from positive charges and terminate at negative charges. The tangent to a line at any point gives the direction of the electric field.

Electric charge is an intrinsic property of matter that causes it to experience force in electromagnetic fields. Charges are either (protons) or (electrons). Fundamental Properties: Quantization: Charge exists in discrete packets; the total charge is an integral multiple of the basic unit ), represented by Conservation:
