When electric current changes direction, it is called alternating current (AC).
A microphone is the device that changes sounds into electric current.
The telephone does that!
AC current (alternating current) like in a wall outlet
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
an electric current that changes it direction or strength repeatedly
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.
AC current (alternating current) like in a wall outlet
An electric current that periodically changes direction is called an alternating current (AC). In AC circuits, the flow of electric charge reverses direction many times per second, typically at a frequency of either 50 or 60 Hz. This is in contrast to a direct current (DC) in which the flow of electric charge remains constant in one direction.
An electric current that rapidly changes directions is known as an alternating current (AC). This type of current flows back and forth in a circuit, changing direction at a specific frequency, such as 60 Hz in many parts of the world. This is in contrast to direct current (DC), which flows in only one direction.
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
