Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field.  The law was initially formulated by Carl Friedrich...

For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...

This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...

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