Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

Electric circuits often consist of several elements, some combined in series and others in parallel. The methods used to analyze series and parallel circuits can be combined to analyze these ...

One of the most fundamental concepts in our profession is impedance. Due to the nuances of the mathematics related to this quantity, the minutia of what is taking place and the associated nomenclature ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...
