An electric current is the measure of what?
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
What describes the direction of the electric current in Alternating Current?
It alternates.
When an electric current flows through a long conductor how does each free electron moves?
The individual electrons will move back and forth, as they do when there is no current. You would have to do very careful statistics to notice that there are slightly more electrons moving in one direction than in the other: the drift velocity (average velocity due to current) of the electrons is typically a fraction of a millimeter per second.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
What is the name of an electric current that flows in one direction?
That's a "direct" current.
What is an alternating circuit?
an electric current that changes it direction or strength repeatedly
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What enables the electric current to move through a material?
The electric current moves in the direction opposite to the flow of electrons by convention.When a potential difference is applied to a material which has "loose" electrons, the electrons move in a direction opposite to the potential gradient and the current moves in the opposite direction to the flow of electrons.This is how current flows in materials.
How does electric current travel?
the flow of electrons in a metal is called electric current . the conventional direction of electric current is shown from positive pole to negative pole
What is difference between current and electricfield?
the direction of current is the direction of electrons move. the dirction of electric field can be negative to positive
How the direction of electric current differs from the direction of electrons in a circuit?
Circular,,,from the word circuit.
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 the electrical current in a circuit?
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
Why electric charge is a scaler quantity?
Current is a scalar if it is given as a scalar - such as 5A. There is no direction connected with this. If it is referenced to a voltage - 5A at 30 degrees lagging the voltage - then it is a vector quantity.
The flow of current in electrodes is in which direction?
The ELECTRONS flow from the negative to the positive terminal. But it is considered that the electric current flows from the positive to the negative terminal.
What is the direction of flow of electric current in an electric current?
DC current
What purpose you use voltage in current?
Electrons cannot flow in a particular direction(current)it moves randomly without external voltage or potential,hence there is no net electric current.hence we need a external potential to drift electrons in a particular direction.
