Text in the illustration

electrons (electricity) travelling along a wire
e⁻
electricity flow can be compared to water flow - if pressure is applied at one end of a pipe (or wire) then water (or electricity) will flow out the other end
water flowing through a pipe

Generated explanation

The illustration explains electrical flow using an analogy to water flowing through a pipe. The upper diagram shows electrons within a wire, with arrows indicating travel to the right. The lower diagram shows a handwheel-operated valve connected to a horizontal pipe, with water discharging from its open right end. Arrows indicate water flow through the pipe, while an arrow above the handwheel indicates rotation. The annotation compares pressure-driven water flow with electricity flowing along a wire; no installation defect is depicted.
