Oliver Kent of Muirhead Aerospace Ltd recently commented on my formula for twisted-pair line impedance (Figure 1). “I am using coated wire with 1.3-mm outer diameter and 0.95-mm inner diameter,” Kent ...

Wired speakers are the go-to for audiophiles looking to get the best audio setup, but that also means trying to determine the ...

Plot a graph of resistance, R, in Ω on the y-axis against length, l, in cm on the x-axis). Draw the line of best fit. We can see from the graph that as the length of the wire, l, increases, the ...

A 5 m length of wire is found to have a resistance of \(40 \Omega\). What is the resistance of each of the following identical wires of different length? Since each wire is identical resistance and ...

Your new project requires a 14 inch trace to carry 100 mA. You can allow no more than 20 mV of drop in the wire. Will an 8 mil trace be wide enough? Your PCB copper plane uses 1 oz copper and is at ...
