Circuits, Voltage, Resistance, Current - Physics 101 / AP Physics Review with Dianna Cowern

I love the comparison of Voltage to the energy potential of lifting a weight against gravity, especially as it relates to batteries.  I've always used an analogy comparing electrical potential in a battery to water in a water tower.  The new analogy comparing electrical potential to lifting a weight in a gravitation field might help people understand in a different way.  Great series!
