Help
The menu item above lists all the pages giving basic information with regard to
electronic and electricity. The horizontal menus, top and bottom give other information.
This purpose of this section of the web site is to help with understanding
alternating current. Sub sections will split this into basics, single phase,
three phase, and higher frequencies. You will need to understand
DC before attempting to understand AC.
An attempt will be made to answer some of these questions.
- What is impedance?
- How can AC which goes backwards and forwards do anything?
- What is a sine wave?
- What is meant by a neutral?
- How do power stations produce electricity?
- How does a three motor work.
- What is power factor correction?
- How do Variable Frequency Drives (VFD) work?
- How does dynamic braking work.
- How does a core balance transformer work
- What is meant by star and delta connections
- What is a star/delta starter.
- What is a three phase induction motor.
