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 ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

The classic low-current technique is the “up-in-the-air” wiring technique, where leads of the components in the critical path or circuit node are soldered together above the board. These component ...

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 ...

Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...

This file type includes high-resolution graphics and schematics when applicable. Recently, an engineer asked for a solution to provide high-side monitoring of a 20-A load with an accurate overcurrent ...

Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...
