PPT-Electric Current Lesson 8

December 9 th 2011 Electric Current is the measure of the rate of electron flow past a given point in a circuit measured in amperes A Think of it in terms of a waterfall If you could count the number of water molecules that drop over the edge every second you could get the rate at which water is flowing past a particular point . Ensure the ultimate safety of your horses, cattle, sheep, livestock, dogs, and other pets with high tensile fence or other electric fencing. Our farm fencing accessories and electric horse fence supplies are also ideal for deterring predators, deer, and other garden pests. 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.
