I used to use a gravitational field analogy when teaching Secondary school physics.
Electrons are equivalent to "balls" with mass. Potential difference equates to a gravitational field (which most people seem to intuitively understand from experience). Balls can roll down slopes of different gradients, and therefore at different speeds, which is analogous to current and resistance.

It worked for me.
