The power source for an electric fence pumps charge from the earth to the fence wire, which is insulated from? - electric fence wire
Country. The ground can conduct electric current. When an animal goes to the wire, get a shock. Can the route through the river flows and give physical motivation. It is a question of rights and confused.Thanks me.

Electric Fence Wire The Power Source For An Electric Fence Pumps Charge From The Earth To The Fence Wire, Which Is Insulated From?

It takes a very high voltage. The earth is a conductor, but still considerable resistance. A high voltage source with a terminal for cable access to a metal rod connected to the earth. When an animal touches the wire with the earth, a current flows through the wire, the skin of the animal's body through the feet, through grounded back through the wetland contribution of metal, metal stake in the new energy source, the completion of the course.
The relatively low voltage, but there's a big shock.
The positive side of food attached to the fence (which is isolated from the earth) and the negative pole is grounded. When an animal touches the fence, a path for electrons from the earth by the animals through the fence and back to eating. In other words, the animal has finished the track.
The use of electricity involved in the events special risks of burns and electric shock [1]. The dangers of electricity (see Table 4.1), depends on the amount of the power frequency, duration, place with the body and the physical condition of the person. The AC 60 Hz is slightly more dangerous than the current frequency of current, high (more than a few kHz are) safer because they flow on the surface of the skin, heart and lungs are prone. The defenses of the body varies according to 300 ohms to about 100,000 ohms, and tensions are still very low, therefore, can cause fatal accidents. The death occurred at voltages up to 24 volts. For currents above the "let go" current (10-20 mA) [2], the person is frozen on the track, and a general trend, rising to a level of approximately 25 mA at the start twitching. Then the person is dismissed on the track or increase current continues to ventricular fibrillation or cardiac arrest (at 50-200 mA), provided that the pathThe current is in the heart.
Current flows through the body to the earth. Electricity always seeks the shortest route to earth.
