Circuits without fields

I have been looking at the new subject guide and there are some interesting changes. The biggee is no options however most of special relativity, thermodynamics, resonance and rotational mechanics plus some astro is now in the core. To make some room for this capacitors and energy production are out. The guide is organised into 5 themes, mechanics, particles, waves, fields and nuclear/quantum. I have begun to  reorganise my text book, the publisher is keen for me to follow the guide order so that means covering circuits before electric fields. At first i wasn't keen but thinking about it, maybe it's not such a bad idea. In fact fields might confuse circuit. To solve circuit problems all you need to know is that current is proportional to pd, you don't have to know why. I bet there are a lot of competent electricians who don't know the charge of an electron.

Circuits are actually now part of the particles theme so I intend to introduce them with an analogy of balls rolling down a slope.
