Apex ;)

Yes, an electric current is the movement of negative charges called electrons.
The pitch of a sound can be determined by its frequency alone.
electric force can act at a distance bbut is stronger when object are closer
Newtons first Law
A short answer:
An electric fence is connected to the ground only when an animal or a human being touches it to complete a circuit from the fence to the ground.
A longer answer:
The wires of an electric fence are not connected directly to the ground because, if that was done, the fence would be shorted out and would not be able to do its job!
This is how an electric fence is actually hooked-up: the electric fence is connected to one side of a specially designed high voltage source and the return side of that source is connected to the ground.
Then, whenever the skin of any animal - or human - touches the wire whilst standing on the ground in bare feet, they get a high-voltage (10,000) DC electric pulse from the electric fence. The shocks are designed to be only enough to make them jump back from the fence, not to "electrocute" them so badly as to cause serious injury or death.
Protons are positive charged particles. Electrons are negative charged particles.
If a home were wired in series, every light and appliance would have to be turned on in order for any light or appliance to work.
