Why human body has more resistance than metal?
Human body has more resistance than metal because it has less conductor for carrying electrons.
Force on a current-carrying conductor?
Torque
What is the relationship between the direction of current and direction of electron flow in a current-carrying wire?
because the current is actually the flow of electrons.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
Can you have only one current carrying conductor in a conduit?
You can have only one current carrying conductor in a conduit, but that conduit must have a slot to relieve the eddy currents that will be created by the transformer effect created by the conductor. It is better to run the neutral or opposite conductor along with the hot conductor together in the same conduit, or through the same penetration, so as to minimize this effect.
Why the wood is not good conductor?
A conductor is something that allows for the movement of tiny charge carrying particles called electrons across the surface. The specific elements that make up wood and the way that its molecules are arranged don't allow for ease of movement of electrons across its surface.
What Created around a conductor when electrons flow through that conductor?
Whenever a charge passes through a conductor, a magnetic field is produced. Hence, whenever a current carrying conductor is placed in a magnetic filed, it will experience a force whose direction is determined by Fleming's left hand rule.
What happen when a current carrying conductor is placed in a magnetic field?
A force will be applied to the conductor. This is the operating principle of the motor.When a current carrying conducter is placed in magnetic field it experiences a force.Reason :- Force(F') on a charged particle(q) moving with velocity v' due to magnetic field(B') around it isF' = q (v'xB') where F', v', B' are vectorsand v'xB' is vector product or cross product which also gives the direction of this Force vector F'.Current, as we know, is caused due to motion of electrons. So, when a current carrying conductor is placed in magnetic field, these moving electrons experience force and so does the Conductor too.If the force on electrons is summed up or integrated over the entire length(L) of a straight conductor. We will end up withF = BIL where I is the current. Direction of this force is determined by cross product of direction of current and Magnetic Field.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
Which law gives the direction of magnetic field due to a current carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
How is it used in determining the direction of the magnetic field around a conductor carrying current?
By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.
What is the Flemings left hand rule?
The direction of force produced on a current-carrying conductor placed in a magnetic field can be determined by this rule. the thumb, forefinger and middle finger of the left hand mutually at right angles to each other, such that the forefinger is in direction of flux, and the middle finger is in a direction of current flow in the conductor, then the thumb indicates the direction of motion of the conductor.
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
What is the purpose of Fleming's right hand rule?
Fleming's right hand rule is used to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field. By aligning the thumb with the direction of current flow, the forefinger with the direction of the magnetic field, the middle finger points in the direction of the magnetic force acting on the conductor.
A current flowing towards the viewer in a cross section conductor is shown by?
Sketch the direction line of force around a conductor which is carrying current away from the viewer and also towards the viewer.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
Why human body has more resistance than metal?
Human body has more resistance than metal because it has less conductor for carrying electrons.
