In three phase systems, the use of transformers with three windings (or legs) per side is common.  These three windings are often connected in delta or...

A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...

This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
