Can you hook a fence charger up in the middle of the fence and have electricity running both ways through the same wire? Also if I run 2 legs off my charger to two separate fences does it split the output joules in half for each fence?
The effect of the energizer being in the middle of the fence instead at one end will be negligible.
It won't be zero effect or immeasurable, but you probably don't have an instrument sensitive enough to measure the difference. Neither do I or most folks.
But, the very minute difference is in your favor. The severity of the shock you or a cow feels depends on resistance. Joules is a measure of energy, and is a 'product of voltage, work, time and resistance in the circuit.
The more resistance between source and measuring point means less voltage, but since the shock doesn't actually occur until the positively charged pulse returns to the negative terminal on the energizer's board, the resistance in the soil is part of the equation.
The further the point from the energizer that the cow gets shocked at means there is more resistance in the circuit. It also means it takes that pulse longer to make the trip from the output of the fence charger, down the wire, thru the cow, out it's feet, into the ground and back to the charger. Can you measure the difference? No, but it's there.
(Joules formula needs voltage, resistance, and work. Amps is not a unit of work--current has to be converted to watts before calculating joules)
