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, ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In my previous article on photovoltaic (PV) systems (“The Highs and Lows of Photovoltaic System Calculations” in the July 2012 issue), I went through methods to calculate the changes in voltage due to ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...
