first of all the voltage doesn't change what changes is the current direction
the way they do it is by using magnet .
electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.

∙ 10y agoWhen a conductor passes through, or 'cuts', a magnetic field, a voltage is induced into that wire. The magnitude of that voltage is proportional to the sine of the angle at which that conductor cuts the magnetic flux. Maximum voltage occurs when the conductor cuts the flux at right angles (sine 90 degrees = 1) and no voltage is induced when the conductor runs parallel with the flux (sine 0 degrees - 0). The direction in which the induced voltage acts depends on the direction in which the conductor cuts the flux; reverse the direction, and the direction of the induced voltage will also reverse.
So, if a conductor is made to rotate within a magnetic field, the voltage generated will vary from 0 V to a maximum voltage in one direction, back to zero, and back to a maximum voltage again, but in the opposite direction.
If you were to view the shape of this generated voltage waveform on an oscilloscope, you will see that it forms a sinusoidal waveform.
The only difference between this simple explanation, and what goes on in a 'real' generator, is that a coil is used instead of a single conductor, in order to produce a larger sinusoidal voltage.

A flow of electrons in a definite direction is called?
Current. Direct Current (D.C) if it is steady. Alternating Current (A. C) changes direction at a constant rate. The frequency for North American AC current from the power grid is 60 Hz, or 60 cycles per second. This would result in the direction of current changing 120 times per second.
What 2 types of currents do you commonly refer to with electricity and what do they stand for?
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
What is alternating current normally produced by?
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
What is the flow of electrons is called?
current
What are the 2 basic types of currents?
The main division is between alternating current (AC) and direct current (DC). AC is universal now for domestic and industrial supply, but DC used to be used in some places in the early part of last century. Automobiles use DC at 12V which is I think universal now. AC in domestic use can be at 50Hz (Europe and many other places) or 60Hz (North America), and can be at either 240V or 120V.
When electrons flow in one direction what is that called?
The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).
What is variable alternating current?
A current which changes its direction of flow again and again is known as alternating current.
Current in which electrons flow in the same direction is called?
It's alternating current
What does ace stands for?
Anthony count Alternating Current - electrons that flow alternately in opposite directions constitute an Alternating current.
Is an alternating current the same as air condition?
No. Not the same. AC means Alternating Current which refers to a type of electrical flow (electrons). The word "Alternating" eaning that the current of electrons changes direction based on its frequency -- e.g., 60 times per second. A/C means Air Conditioning and refers to a machine that cools the air.
What is the differences between direct circuit and alternating circuit?
The main difference between direct current (DC) and alternating current (AC) is the direction of the electrical flow. In a direct current circuit, the flow of electrons is in one direction, from the negative terminal to the positive terminal. In an alternating current circuit, the flow of electrons changes direction periodically, typically at a fixed frequency, resulting in an oscillating current flow. AC is widely used for electrical power distribution, while DC is commonly used in batteries, electronic devices, and certain applications like electric vehicles.
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..

What does AC mean about current flow?
AC means Alternating Current. Alternating Current changes direction constantly, usually at 60Hz (US, Canada, and others) or 50Hz (UK and others).
What does AC and DC stand for in electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
