What does an electric current act like when it flows through a wire?

it depends on the frequency of the current in question. the higher the frequency, the less depth in the cross-section the current flows. this is termed skin depth.

Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is a sentence with the word electric current in it?
The electric light bulb would not turn on because it was burnt out.
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What name is given to the property of metals that allows electricity to pass through it?
I believe its a conductor, because an insallator is like a stirofoam cup for example, as it keeps the heat in the cup without burning your hands. An example of a conductor is a piece of metal because it is able to pass an electric current through the metal.
How can use of a fuse or a circuit breaker prevent a fire in a building?
The wiring in a building, is designed to take the current to devices, when working properly. If a device develops a short circuit, the current is massive and unlimited. Passing massive amounts of current through thin cables will make them heat up, just like the filament in a lamp. This will cause a fire. A fuse is simply a thin wire, that is designed to burn up, when too much current flows through it. It is a controlled burn, inside a specially designed container, at a specific location. As the fuse is in the supply line, when it breaks, the power is also broken and everything returns to a safe situation. A breaker uses a bi-metal strip or coil to monitor the current and tip a switch when too much current flows. Breakers however can be reset and not normally destroyed by a fault.
What does an electric current act like when it flows through a wire according to Christian Oersted's hypothesis?
a magnet
What does an electric current act like when it flows through a wire according to Hans Christian hypothesis?

A complete path for electricity to flow?
currents can be thought of simply by flowing through a wire, though not always the case. It is convenient to think of current density which is the amount of current flowing through a cross sectional area, like water through the opening of a pipe, since electric current flows through many 3-dimensional objects.
How does an electric current produce light?
By heating a metal wire called a filament. In a light bulb (lamp) the electric current flows through a tungsten filament which glows white hot giving off light.
What is a large stream of moving water that flows through the ocean?
The stream of water which flows like a river through the ocean is a current. The Gulf Stream is the most significant such current which flows from the tropics to the northern latitudes.
What type of current flows through an electric current?
Current is the flow of electrons. This could be DC (direct current like what you find in a battery) or AC (alternating current, what you find in a regular plug for example). Current is measured in Amperes or amps. And if you have the unfortunate chance of being shocked, amps are what could actually harm you or kill you.
Is electric current flows like water in a river bed a alliteration metaphor simile or hyperbole?
Simile
What wire coil acts like a magnet when a current flows through it?
Electromagnet
How is the electricity like a river?
Electric current flows like water in a river flows. If the river is deep, there is greater current but slower. If the river is shallow, the current is faster, but the volume of water is greater. The same analogies can be used with electricity.
What is an electricity shock and what happens?
An electric shock happens when an electric current flows through the body. It causes muscular spasm and associated pain. The severity of the shock depends on how much current there is. Currents above about 35 mA can be fatal if they reach the most sensitive muscles like the heart.
