Understand how much distance I have to move to cause a voltage difference of 1 V
a) Far away from the source charge b) Very close to the source charge.
Connect that finding with Conservative Force / Field concepts
Equipotential Lines for two charges separated by a distance
$E= - \frac{dV}{dr} \; \; F = -\frac{dU}{dr}$
a) oppositely charged b) same charged
Why E perpendicular to surace

What is a capacitor? What is that 80V in the Label? What is the resistor doing here?
Capacitor Basics
Change the battery voltage and see what happens to
the charge and the voltage in the capacitor, Q = C V
Change the area and gap between the plates and see what happens
to the Capacitance value, C = epsilon_o A / d
