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 ...

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 ...
