You know about coaxial cable (Fig. 1). We all use it in one form or another, and it seems simple enough. But while modern cable products are better than ever, there are some real subtitles in their ...

Coaxial cable: Coax is good for short wire runs in low-noise environments. Its thick copper construction yields low signal losses. As an unbalanced transmission-line, its interference immunity is poor ...

You can use a multimeter with capacitance-measurement capability to measure the length of wire or cable to an open circuit. The capacitance of a pair of wires (or a wire to a shield) is directly ...
