Why doesn't? Is that what you mean? If so it is because then like a subway it will use a tone of energy always has to have electricity running threw the track it is also a danger to pedestrians and cars or anything like animals ext. We are better off running the trains on other fuels.
I don't know what "iron gold" is, but electricity will flow through any metal pretty well.
Your question is its own answer.
A Resistor
Insulators.
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
Leather is not a good conductor of electricity. It is an insulator, meaning it does not allow electricity to flow through it easily.
It is used as part of the signalling system, so that the rail comapny knows where the trains are.
I believe that they flag the trains to warn them of work being done on the tracks or signals being worked on. Tracks need to be constantly inspected so I believe that they must use flagmen in order to keep the flow moving while still being able to inspect properly
Electicity flows almost at the speed of light of 186,000 miles per second. In one mile, flow takes a little more than 1/186000 = about 6 millionths of a second
In an electrical circuit, electicity moves from the positive (+) end of the power source to the negative (-) end.
Yes, electricity is a form of energy resulting from the flow of electric charge. It is often used to power various devices and systems in our daily lives.
Electric current - a movement or flow of electrically charged particles, typically measured in amperes.In a conductor, current flow is via a drift of free electrons in the metal. the actual drift rate may be slow, the electric field that drives them itself propagates at close to the speed of light, enabling electrical signals to pass rapidly along wires.See related link belowElectricity can flow through a conductor because it allows the electrons to move freely through the object. With an insulator, electrons cannot move.
Charge flow through a circut
Static electricity and current electricity are both forms of electrical energy. They both involve the movement of electrons, but in static electricity, the charges accumulate on an object and do not flow, while in current electricity, the charges continuously flow in a circuit.
of course liquid can flow through a pipe?
yes charge flow through the circuit
Yes, electricity can flow through metal.
