A short non-mathematical description of the analogy between fluid flow in pipes and electricity flow in circuits, comparing batteries to pumps, current to flow rate (liters-per-second) and voltage to pressure. At the end the electric field is introduced as the 3-dimensional distribution of voltage in space.
