The amount of current depends on the voltage and the total resistance ofthe circuit. Livestock respond to the resulting current flow, not tovoltage. The amount of current depends on the voltage and the total resistance ofthe circuit. Livestock respond to the resulting current flow, not tovoltage. Livestock respond to or can feel current.
Voltage is measured to estimate the amount of current thatcould flow through an animal.
When an animal touches twopoints at different voltages, current flows because the circuit iscompleted. Behavior response is a change in behavior, usually observed as an animal avoiding an object or area. An example would bean animal standing on a sloppy wet floor or earth and touching agrounded metal watering device with its nose. A more typical farm condition,withan animal standing on concrete, would require voltages that are abouttwice as high to get the same current level. The table above is for 60 cycle electricity as used onfarms.
