A device that reverses the direction of electric current is called a switch or a commutator. These devices can change the flow of current by opening or closing a circuit in the opposite direction. Such devices are commonly used in electrical systems to control the direction of current flow.
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
Increase or decrease in potential results in the change in direction of the flow of electric current.
No, the continuous flow of charge in a circuit is called electric current. Direct current (DC) refers to the flow of electric charge in a single direction, whereas alternating current (AC) changes direction periodically.
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.
Current is the flow of electric charge through a conductor, measured in amperes (A). It is commonly symbolized by the letter 'I' in equations. Current can be either direct current (DC), where the flow is in one direction, or alternating current (AC), where the flow changes direction periodically.
from positive terminal to negative terminal
Cooling fans use electric motors which operate by magnetism. As the direction of the current flow reverse, the magnetic poles reverse and hence the change in direction.
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
An electric current that changes direction is called an alternating current (AC). In an AC circuit, the flow of electrons changes direction periodically, typically at a frequency of 50 or 60 Hz. This is in contrast to direct current (DC), where the flow of electrons is constant in one direction.
