I knew I was missing something important when as a mid-level electrical engineer, I used to wonder which voltage value I should be using in my calculations. Was it 110V, 115V, 117V, or 120V? Was it ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

This whitepaper compares single phase and three phase circuits from the component count, stress level and complexity standpoints. The document shows that on most cases, single phase circuits are the ...

A balanced Y-connected load of (300 + j100) Ω is supplied by a three-phase line 40 km long with an impedance of (0.6 + j0.7) Ω per km (line-to-neutral). Find the voltage at the receiving end when the ...
