  • What is a constant electric field?

    Firstly, the Electric field "E" is the slope of the potential, i.e., E=?dVdx. Therefore "constant electric field" means the potential is either increasing or decreasing at a constant rate (along the space).9 avr. 2016

  • Does electric field have a constant?

    Thus, the electric field is constant between plates because plates generate a constant electric field in the same direction.

  • What is the equation for the constant electric field?

    We can use the equation E = k Q r 2 E = k Q r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case. E = k Q r 2 = ( 8.99 × 10 9 N ? m 2 /C 2 ) ? 1.5 × 10 ? 9 C ( 0.035 m ) 2 = 1.1 × 10 4 N/C.
  • Electric field strength in a radial field is not constant. As the distance from the charge r increases, E decreases by a factor of 1/r.
