What is the relationship between current and frequency in AC circuit?

Two words: skin effect. Now let's chat. Picture a wire with DC flowing through it. We are going to look at a cross section of the wire without interrupting current flow. Make sense? Picture it. When current flows in a wire in only one direction (DC), it uses all the available metal in the wire. Current flow in the middle of the wire will be about the same per unit of cross sectional area as current flow will be near the outside of the wire. Let's switch our DC for some AC. AC (alternating current) will flow in one direction for a while and then reverse direction to flow the other way for a while. Such is AC. And AC will cause current flow that uses all the available cross sectional area of the wire just as DC does, but only at low frequency. At higher and higher frequencies, current flow in the wire will shift away from the center and be more concentrated near the surface of the conductor. Near the skin of the conductor. AC of higher frequencies will promote current flow by skin effect, and that is the effect of frequency in AC current flow.

What refers to electric current when electrons always flow in the same direction in the wire?

When electrons always flow in the same direction in the wire it is known a DC (direct current).

What is a jerky flow of electrons across a wire called?

The term jerky flow needs to be expanded upon to answer your question. It could mean alternating current or pulsating DC current.


Does a person stick to the wire conducting alternating current or direct current?

stick to DC and AC where the voltage exceeds a specific limit and if current flow path is there .


What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?

The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.


What is the direction of flow of electric current in an electric current?

What is a current consisting of charges that flow only in one direction called?

A Direct Current or DC direct current is a current consisting of charges that flow only in one direction.


Why DC supply is need in thyrister?

because thyrister doesn't allow the current to flow unless there is a current flow into the gate. this current must be dc, and the rating of this current depends on the type of thyrister.

How can identify AC and DC?

DC is direct current, and is characterized by its steady flow of current. AC is alternating current. It is characterized by increases and decreases in the current.


Is there actually current flowing through the return wire?

Yes, there is a current flow through he return wire in a closed circuit. The only time there is no current flow through the return wire is when the circuit is open.
