Neutrons have no charge.
Not enough information. WHICH fuse blows out???
____________ charges repel each other.
like
It is in parallel, so one light can be on while others are turned off.
It is measured in ohms. It is the opposition of movement of electric charge. It is related to voltage and current by Ohm's Law. Resistance is what builds up pressure and it can also generate heat as with friction.
The pitch of a sound can be determined by its frequency alone.
In a series circuit the current is the same at every point. This is Kirchoff's current 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.
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
