What else can I help you with?
what rule is applied in case of dc motor?
You may be thinking of Fleming's Left-Hand Rule (for conventional current flow) or Fleming's Right-Hand Rule (for electron flow), devised by academic Sir Ambrose Fleming, as a aid for determining the direction of the resulting force acting on a current-carrying conductor within a magnetic field, when the direction of current and the direction of the magnetic field are known.
Why cannot the B-field of an infinitely long straight current-carrying conductor have a component in the direction of the current?
As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
A circuit carrying current in one direction is called a?
A circuit carrying current in one direction is called a direct current (DC) circuit. In a DC circuit, the flow of electric charge is constant and does not change direction. This is in contrast to an alternating current (AC) circuit, where the flow of electric charge changes direction periodically. DC circuits are commonly used in electronics and power transmission systems.
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
What is the relationship between the direction of current and the direction of electron flow in a current carrying wire?
the directions are opposite to each other
What is the relationship between the direction of current and direction of electron flow in a current carrying wire?
the directions are opposite to each other
What is the direction of the force on an electron that is moving alongside a wire that is carrying a current in the opposite direction?
The force on the electron would be perpendicular to both the direction of its motion and the current flow in the wire. This is described by the right-hand rule for magnetic fields, where the force would point in a specific direction based on the orientations of the current and the electron's motion.
What is the direction of the magnetic field around a current-carrying wire?
The magnetic field around a current-carrying wire is circular and perpendicular to the direction of the current flow.
What is the direction of a magnetic field around a current-carrying wire?
The direction of a magnetic field around a current-carrying wire is circular, wrapping around the wire in a clockwise or counterclockwise direction, depending on the direction of the current flow.
In what direction is a force exerted on a current-carrying wire when it is placed in a magnetic field?
The force exerted on a current-carrying wire placed in a magnetic field is perpendicular to both the direction of the current and the magnetic field.
What is electron movement referred to as?
Electron movement is referred to as electric current. When electrons flow through a conductor, such as a wire, they carry electrical energy from one point to another. The direction of current flow is opposite to the direction of electron movement.
What technique is used to determine the direction of the magnetic field around a current carrying conductor?
The right hand rule is a simple way to find out the direction of the field surrounding a current carrying conductor.Point your right thumb in the direction of the current in the wire (which flows from high to lower voltages) and curl the other fingers as if around the wire; the curled fingers define the direction of the magnetic field generated.CommentIt might be worth pointing out that the above answer applies for conventional flow, not electron flow.
What does the right hand rule indicate about the direction of a magnetic field when your fingers are curling around a current-carrying wire?
The right hand rule indicates that when your fingers curl around a current-carrying wire in the direction of the current, your thumb points in the direction of the magnetic field.
Why the current is flowing in opposite direction in cables?
the charge of the electron is negative
