1
New cards

what is electric field strength

  • Force per unit charge (or voltage per unit distance) on a positive test charge placed at that point in the field

  • E = F/Q = V/d

2
New cards

what is electric potential energy

  • The work done in bringing two charges from infinitely far apart to their position

  • EPE = kQq/r

3
New cards

what is electric potential

  • Work done per unit charge in brining a small, positive test charge from infinitely far to a position in the field

  • Ve = W/q = kQ/r

4
New cards

permittivity

  • A materials ability to transfer an electric force or field
