Do you mean "can current flow in both directions"? In theory, yes.
That refers to AC (alternating current). A direct current flows only in one direction; an alternating current changes its direction all the time. The "frequency" refers to how often the current changes direction. It is expressed in hertz (Hz), which means the same as cycles/second.
The direction of the magnetic force on the current in (a) is perpendicular to both the direction of the current and the direction of the magnetic field.
A diode is an electronic component with the characteristic that its resistance is not constant, but depends on the magnitude of the current through it. An ideal diode has zero resistance to current in one direction, and infinite resistance to current in the reverse 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.
When there is a large current in the direction shown, each compass point will point in the same direction as the current.
Direct current (DC) is the term used to refer to current that flows in one direction and does not reverse its direction. This is in contrast to alternating current (AC), which changes direction periodically.
AC, Alternating Current.
When electric current changes direction, it is called alternating current (AC).
When the flow of current is aways in one direction it is known as direct current.
To determine the direction of current in a magnetic field, you can use the right-hand rule. Point your right thumb in the direction of the current and curl your fingers in the direction of the magnetic field. Your fingers will then point in the direction of the force acting on the current.
The current direction is from left to right.
