In physics, the phrase point charge refers to the fact that linearly charged objects have a small size in contrast to the distance between them. The force that exists between two point charges is described by Coulomb’s Law. Electric field lines are always parallel to the conductor’s surface.There are no two electric field lines that cross each other.The direction of electric field intensity at any point is determined by being tangent to the electric field line.They begin with a positively charged body and end with a negatively-charged one.Lines of the electric field are continuous curves.where E is the electric field’s strength,.The electric field’s magnitude is calculated using the formula: The lines must point radially outward, away from a positive charge, or radially inward, toward a negative charge. Electric fields are a vector quantity represented by arrows pointing toward or away from charges. If the charges are far enough apart, the electric field can be approximated as 0 for practical purposes. The electric field exists everywhere in space and can be studied by introducing another charge into it. Electric FieldĪn electric charge creates an electric field, which is a region of space around an electrically charged particle or object where the charge feels forced. Metals, the Earth, and human bodies are all conductors, whereas porcelain, nylon, and wood are all insulators, providing substantial resistance to the flow of electricity through them.
