Explanation: Current flows counterclockwise in this circuit. Using the right hand rule for conventional current in the wire, the right thumb points along the wire and points directly into the wire at the bottom of the circuit.
In which direction does the current flow?
The direction of an electric current is, by convention, the direction in which a positive charge would move. Thus, the current in the external circuit is routed away from the positive terminal and to the negative terminal of the battery. The electrons would actually travel in opposite directions through the wires.
Is the clockwise current positive or negative?
In physics and mathematics, the right-hand rule is commonly used, making it negative. … This is positive for anti-clockwise rotation (seen from above) and therefore negative for clockwise rotation.
In which direction does current flow in a magnet?
The recognized direction of a magnetic field is from its north pole to its south pole. This direction can be inferred by holding the current-carrying conductor in the left hand with the extended thumb pointing in the direction of electron flow from negative to positive.
If the current flow is clockwise, is the direction of the magnetic field generated?
That is, if the direction of the magnetic field is towards you from one end, then the direction of the magnetic field from the other end is away from you and vice versa. The lines of magnetic force enter through the area where the current flows clockwise and exit through the area where the current flows counterclockwise. 8th
Does the current flow from minus to plus?
The flow of electrons is called electron current. Electrons flow from the negative pole to the positive pole. … Conventional current flows from the positive pole to the negative pole.
Does the stream matter?
The direction of the current is opposite to the flow of electrons. Electric current has both magnitude and direction, so ideally it should be a vector.
Does current flow clockwise?
Explanation: Current flows counterclockwise in this circuit. Using the right hand rule for conventional current in the wire, the right thumb points along the wire pointing to the left at the top of the circuit.
In which direction, clockwise or counterclockwise, does an electron travel through the wire?
Electrons move in a direction opposite to the direction of the electric field, so they travel counter-clockwise through the wire.
How to reverse the direction of the current?
Of course, the direction of the current is controlled by the polarity of the voltage. So to change the direction of rotation, we can simply reverse the voltage, causing the current to flow in the opposite direction, changing the force 180 degrees and driving the motor backwards.
Can current flow back into a battery?
A battery will charge (when its chemistry allows) when the current is reversed. … Diodes also only work as voltage sources when current is flowing in the most positive terminal. So, in theory, you have to be willing to let current flow in both directions through a voltage source.
Should your thumb be pointing when applying the right hand rule?
The right-hand rule dictates the following procedure for choosing either direction. If the thumb, index, and middle fingers are perpendicular to each other (with the index finger pointing straight), the middle finger will point toward c when the thumb represents a and the index finger represents b.
In which direction does the magnetic force act on the wire?
The magnetic field exerts a force on a current-carrying wire in a direction given by right-hand rule 1 (the same direction as on the individual moving charges). This force can easily be large enough to move the wire, since typical currents consist of very many moving charges.
