This is more of a personal thing I have, but I've always thought of the analogy you use being the other way around - the gearing vs. transformer mutual inductance.

I've always thought of current as the high torque low speed gear, and voltage being high speed with little push behind it. My teachers have compared it to two hoses, a high voltage hose with a small diameter moving water very fast, versus a large hose with a slower flow but much greater volume moving through it.

Just wondering what you thought, as this seems quite a bit backwards to my mind.
