PPT-Today: Chapter 23: Electric Current

Still waiting for scantron results Electric Current Is the flow of electric charge ie charged particles usually electrons between regions of different electric potential When there is no potential difference there is no charge flow no current. Ranchers, farmers, and other horse owners know how important a safe environment is to raising horses. While it is essential to keep horses within the boundaries of your property and safe from would-be predators, these valuable animals can easily be injured by fence railing that cracks or splinters. Current. Electric current. Electric current. . is the rate of electron flow past a specific point in the circuit (how . fast . electrons pass . through a . point in the wire).. The symbol for electric current is . We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products. The next few slides are not on your note. They are just interesting. Electric Fish, Eels, and . Rays. For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . A . force. is a push or pull exerted on an object..
