The resistance of copper traces on printed circuit boards impactspowerdistribution,signal integrityand overall circuit performance. Accurately calculating trace resistance is therefore an important skill for PCB designers. This article will provide an overview of the key parameters and formulas used to dete...
Photo: Measuring resistance with a multimeter. Using a multimeter like this one, you can automatically find the resistance of an electronic component; the meter feeds a known current through the component, measures the voltage across it, and uses Ohm's law to calculate the resistance. Although ...

How to Calculate Short Circuit Current of Circuit Breaker: Calculating the short circuit current involves specific formulas and understanding material limits, ensuring CB designs can handle faults safely. When a short circuit fault happens, a largecurrentflows through the system, including thecircuit bre...
the impedance of the electrodes is very low due to the high conductivity of metals, so the voltage drop across them can be neglected. As a result of these considerations, the circuit in Fig.1c can be represented, to a very good approximation, by a capacitor, a resistance, and a second...
With respect to chloride resistance, cement paste is the “active part”, and both aggregates and sand can be considered “inert”. The total chloride content or “height” of the chloride profile is therefore largely determined by the binding capacity and amount of the cement paste in the ...
Now I have the problem to calculate the mutual inductance of two or more coils which are placed into the media with electric conductivity range from 0.0005 S/m to 1000 S/m. I created a simple model but don't know how to extract the inductance matrix of the coils system. Furthermore, ...
