As much as you want....... maths would be your answer :-)
If you have 5-10 miles of wire then you would have 7500 V. This is suitable for farms up to 5-25 acres.
10,764 feet
Well, first you need to know the length of barbed wire in a roll. Then you need to know the perimeter of the fence (in feet or metres) you are going to build around that 180 acres. Then, calculate it this way: (length of barbed wire in one roll) x (perimeter of fence of 180 acres) = (total length of wire needed for "n" ft. (or m) of fence perimeter of one strand) (total length of wire needed for "n" ft.(or m) fence perimeter of one strand) x 5 = (Grand total length of wire needed to fence 180 acres) (Grand total length of wire needed to fence 180 acres) / (length of barbed wire in one roll) = (# of rolls needed for a five-strand barbed wire fence for 180 acres)
The electric fence.

For a three-acre square-shaped lot, you'd need a minimum of about 1,446 feet of fencing.
Yes the electric wire needs to run all the way around.
sort of you need 2 acres per horse in a 2-strand wire fence.
80 acres is 880 x 440 feet. Depends on how many cattle and how rough they are on your post settings. Most people around here in Oklahoma put their t-posts roughly 16' apart. This will take 164 posts. A roll of barbed wire will usually run a quarter of a mile of fence. So on a typical 5 wire fence it will take 30 rolls of barbed wire.
A generator runs electricity through a wire thus electrifying it.
You need an electric fence controller, first off. The purpose of an electric fence is to scare whatever touches it into staying away. If you try to make one by wiring it to mains power, you will just kill whatever touches it. You can get a controller at Tractor Supply Co. After procuring a controller, running an electric fence is a simple matter of stringing wire on insulated posts. You connect the controller to your fence and ground, and there you have it. Talk to the salesperson at the Tractor Supply store. They will have controllers, wire, insulators, posts that can be easily installed, gate handles, and whatever else you need.
electric fences require the conductor wire to complete a circuit (more than 1 for backup)
