Synonyms: electrical-resistance

Anything about electrical resistance, i.e. the electrical parameter that relates currents in conductors and the voltage drop they generate. It's also a measure of the opposition that a conductor exerts on the currents flowing through it.

Resistance is the main parameter of a resistor, but it's also a parameter used in other situations like the description of parasitic effects in the practical realization of circuits (e.g. the resistance of the winding of an inductor or the resistance of the traces on a PCB).

Q&A Changing PCB trace width once signal-to-noise ratio is high

I'm designing a PCB to filter and amplify a differential body signal with amplitude 5 mV up to 5 V. The first part of the circuit consists of a first order highpass filter to remove any DC componen...

Q&A estimation of pogo pin resistance

Is there a scientific way to estimate the resistance of a pogo pin? If it was a solid cylinder or wire one could calculate the resistance: R = ρ × L / A But a pogo pin is hollow inside, the sp...
