Presentation transcript:

Brian Parkhill Patterson Pd. 2A

What is alternating current? An electric current in which the direction of flow of the electrons reverses periodically having an average of zero, with positive and negative values.

What are the parts of alternating current? 1. Field 2. Armature 3. Prime mover 4. Rotor 5. Stator 6. Slip rings

How does alternating current work? AC voltage may be increased or decreased with a transformer. Using higher voltage leads to more efficient transmission of power.

Uses & why The main generators in nearly all electric power plants are AC generators. This is because a simple electromagnetic device called a transformer makes it easy to increase or decrease the voltage of alternating current.
