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.
Moving a wire through a magnetic field does not create a current flow in a wire?
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
What is Another name for DC current?
Another name for DC current is direct current. It refers to the flow of electric charge in a single direction, as opposed to alternating current (AC), where the flow of charge periodically reverses direction. DC current is commonly used in batteries and electronic devices.
What is charged by having a one way current flow through it?
A battery is charged by having a DC current flow through it.
What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
What refers to electric current when electrons always flow in the same direction in the wire?
Direct current (DC) refers to electric current where electrons always flow in the same direction in the wire. This is in contrast to alternating current (AC), where the flow of electrons periodically reverses direction. DC is commonly used in batteries and electronic devices that require steady and constant voltage.

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 flow of current through a wire known as?
The flow of current through a wire is known as electrical current.
What are the differences between DC wire and AC wire, and how do these differences impact their performance in electrical systems?
DC wire and AC wire differ in their ability to carry direct current (DC) and alternating current (AC) respectively. DC wire is designed to carry a constant flow of current in one direction, while AC wire is able to handle the rapid changes in current direction that occur in an AC system. These differences impact their performance in electrical systems as DC wire is more efficient for transmitting power over long distances with minimal loss, while AC wire is better suited for powering devices that require frequent changes in current direction, such as household appliances.
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 a current consisting of charges that flow only in one direction called?
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
What is the direction of flow of electric current in an electric current?
DC current
What is a common wire in a dc system?
A common wire in a DC system is a wire that serves as a return path for the electrical current to flow back to the power source. It is typically connected to the negative terminal of the power supply and completes the circuit for the electrical devices to function properly.
What is the direction of current flow in a DC circuit?
In a DC circuit, the direction of current flow is from the positive terminal of the voltage source to the negative terminal.
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.
