In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced.  In particular...

Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...

Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...

When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...

One of the comments on my Motor Starting Series was asking for something on duty cycles. Here it is. As a purchaser of a motor, you have responsibility...

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...

This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.

It starts with me reading one of the Horrible History books with my son (Groovy Greeks). Arrows were mentioned which lead to the discussion of the bodkin...

Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...

I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
