Series Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate and predict electrical quantities and capacity. Using a direct current (DC) series circuit as ...

Parallel Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate electrical quantities and capacity. Using a direct current parallel circuit as an example, ...

As your career advances, it’s crucial that you understand how to properly perform basic branch-circuit calculations and select appropriately sized branch-circuit conductors. You must also know how to ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...

DNA contains the genetic code that makes humans different from other species of animals and even from each other. Researchers, however, have discovered other uses for the so-called blueprint of life.
