How does the joule relate to the performance of an electric fence charger?
A. It doesnt. It would take a ten page letter to explain all the factors which make an electric shock effective. The joule does not measure the effectiveness of electric shock. The joule is a mathematical equation of Voltage x Amps x Joule. The longer the on-time of the pulse, the higher the joule rating will be and the longer the on-time the less safe the fencer is to use and the less effective. The joule is not the correct way to measure the performance of any electric fence charger because the joule does not consider peak current value or on-time which are key factors in the effectiveness of a fencer, therefore, the joule cannot define true shock effectiveness or fencers safety. What controls livestock is voltage and amperage. You must have voltage in order to force electricity through the conductor (fence wire) as well as vegetation touching the fence, etc., and you must have current in order for the livestock to feel that shock. Joules or heat has nothing to do with it. The most e
