HideShow resource information
• Electric Fields
• Electrostatic Force
• Definition by Coulomb's Law
• Electric Field Intensity
• In a Uniform field (-dv/dx)
• In a spherical field  q/4??r²
• Field Intensity near some specific objects in space
• infinitely large 1.conducting 2. non conducting plate
• Infinitely long conducting rod
• Conducting loops
• Conducting and Non Conducting spheres (Hollow and Solid)
• Electric Potential
• Definition
• work done to bring a unit positive charge to a point from infinity and is a scalar
• Potential Energy is the energy of a charge Q in a point of potential q
• Positive charges prefer Low potential point
• Negative charges prefer high pot. points
• Gauss' law
