Theory of Electricity
It is essential for anybody who wants to understand refrigeration to also understand the workings of electricity.
It is a well known fact that the majority of service calls are actually electrical component problems rather than faults in the sealed refrigeration system itself.
It is not necessary to go into indepth detail in the physics of electricity but a basic background is required to deal with common faults.
We will try and gain a basic understanding of:
How it is produced and sent to your home.
What Electricity is.
Understand what an amp, volt, watts and resistance are.
Understand conductors and Insulators.
Ohms Law
A basic undertanding of circuits and diagrams.
