WebThe Commutator. The answer is to use a commutator. This device prevents the wires from twisting. More importantly it actually allows the coil to keep rotating in one direction! The one shown is a split-ring commutator. It has two halves, each connected to the power supply, completing the coil circuit. The coil is able to turn smoothly around it.

WebApr 21, 2024 · Electricity is the flow of electrons through a wire. When lots of electrons flow in the same direction we call this current. DC electricity means the electrons flow in just a single direction, from one terminal of a battery directly to the other. If we reverse the battery then the current will flow in the opposite direction. Electricity Basics WebBoth AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. inyector gas natural
