If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
A magnetic field can induce an electrical current in a wire.
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
A current in a wire.
It is called electrical current.
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
as a cu wire is a conductor, electrical current does go through it, but some of the electrical energy gets converted into heat energy, and that is why the wire aslo heats up a bit.
An electrical tester is tool used to check if a wire is producing an electrical current. Usually you will just hold it to the end of a wire, if an electrical current is being "induced" a light will glow on the tester, this is a live wire.
The flow of electricity is called electrical current.
Current is known as the flow of an electrical charge. This is carried by moving electrons in a wire.
The black wire is the hot wire through which the electrical current flows to the appliance. The left over voltage which is usually zero flows back to the main circuit panel through the white neutral wire where it flows to ground.
increase
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
