They always make closed loops.
Electric field lines can either form closed loops or they can start and finish on isolated electric charges. Magnetic field lines always only form closed loops.
True
an insulator
voltage
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.
False. The atom that has the same number of protons as it has electrons is a neutral atom.
