What is the difference between a volt, an amp and a joule?
A. Voltage is a measurement of electrical pressure. It can be compared to water pressure in that the push that carries electric current over a wire the way water pressure pushes water through a pipe. When you or an animal receives a shock it is not voltage that you feel, it is the amperage or current. Amperage is a measurement of electrical current. It is the amount of electrical current or amperage that determines the intensity and severity of the shock you feel. The more amperage contained in the pulse of electricity on the fence, the more intense and severe the shock. A joule is a unit of electric energy. It is basically a combination of how the three variables of voltage, amperage, and on-time are combined to produce energy. One joule is equal to one watt of power for one second of time. Q. Why do I lose charge when weeds touch my fence? A. When weeds touch an electric fence they draw a specific amount of voltage and amperage from the fence to the earth. If a lot of weeds touch the
