Lesson 4

Cards (13)

  • Work must be done to move a charge in an electric field created by a point charge or a continuously distributed charge.
  • Electric Potential
    Movement of positive charged particle in uniform electrical field.
  • Electric Potential
    The electric potential at a point is a scalar quantity. It could be negative, positive, or zero, depending on the sign of the charge.
  • Electric Potential
    At a point near a positive charge, it is positive.
  • Electric Potential
    At a point near a negative charge, it is negative.
  • Electric Potential
    The electric potential at any point in an electric field (E) is electric potential energy per unit charge at that point.
  • Electric potential equation
  • Electric potential is designated as = V
  • Electric Potential Equation
    V = electric potential
    U = electric potential energy
  • Electric Potential
    If a positive test charge moves in the direction of the electric field, the field does positive work on the charge. The potential energy decreases.
  • Electric Potential
    If a negative test charge moves opposite the direction of the electric field, the field does positive work on the charge. The potential energy decreases.
  • Electric Potential Difference

    Potential difference is the difference between the potentials between two points in the electric field.
