Short-circuit currents represent a tremendous amount of destructive energy, which can be released through electrical systems under fault conditions. Baseline short-circuit studies should be performed ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, ...

Based on the 2020 National Electrical Code. Part 1 of this two-part series taught you how to calculate branch-circuit loads. Now let's review how to perform feeder and service load calculations.

The electrical panel, also known as the service panel, is the control center for all the electrical circuitry in a residence. Today’s panels are bigger than earlier versions. They have to be, because ...

Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

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, ...
