Basic Electronics - Current
Current is what flows through a wire. Think of it as water flowing in a river. The current flows through wires from one point to another point just like water in a river. Current flows from points of high voltage to points of low voltage. Current can be shown in circuit diagrams by using arrows as in Figure 1. The arrow shows which way the current is flowing. An I is included beside the arrow to indicate current.
