6.2.3: Uniform electric field

#6.2.3a

uniform electric field strength; E=VdE = \dfrac{V}{d}

#6.2.3b

parallel plate capacitor; permittivity; C=ε0AdC = \dfrac{ε_0A}{d} ; C=εAdC = \dfrac{εA}{d} ; ε=εrε0ε = ε_rε_0

Learners are not expected to know why the relative permittivity εr≥1ε_r ≥ 1 .

#6.2.3c

motion of charged particles in a uniform electric field.

Learners will also require knowledge of 3.1, 3.2 and 3.3

6.2.2
Coulombs law
6.2.4
Electric potential and energy
