Not enough information. WHICH fuse blows out???
A closed path through which a current can flow is called a circuit.
they show wich way iron shavings would align themselves
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.
Heat produced by the circuit, current
A magnetic field line shows the direction a compass needle would point.
Power (Watts) = Current (Amps) * Voltage
Power = 22Amps * 240 Volts
Power = 5,280 Watts
There are a couple of ways to increase the strength of a copper electromagnet. You could increase the current going through the wire or wrap more wire around it which increases the strength exponentially. You could also put in a soft iron core such as a nail which in essence becomes a magnet and increases the strength of the magnet.
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.
Like charges repel each others.
The force between charges decreases as the distance between them increases.
False. The atom that has the same number of protons as it has electrons is a neutral atom.
