A liquid dispenser securable about a user’s limb for storing and dispensing a liquid and a method for dispensing the liquid. The spring clip portion includes two opposed electrical contacts at least one of which is resiliently biased toward the other. The particulates can be metals, inorganic compounds, organic compounds and composites. The capacitor comprises a lower electrode, intermediate electrode and upper electrode. The preconditioning circuit adjusts the floating phase coil tap voltage to compensate for an amount of voltage substantially equal to an amount of voltage by which a voltage at the center tap deviates from zero.
