What is the difference between the movement of the two electrons between the two types of currents?

• There's no difference.

• An Alternating Currents electrons move in one direction while a Direct Currents electrons move back and forth.

• An Alternating Currents electrons move back and forth while a Direct Currents electrons move in one direction.

• An Alternating Currents electrons move back and forth while a Direct Currents electrons don't move at all.

What is an Alternating Current?

• An electric current that never changes direction.

• An electric current that changes direction many times.

• An electric current that has no frequency.

• A current that has no electrical properties.
