Which component is not typically found in a standard coaxial cable?

A standard coaxial cable consists of several key components designed to transmit electrical signals effectively while minimizing interference. The core conductor is the central wire that carries the signal. Surrounding this conductor is insulation, which serves to prevent signal loss and protect the inner conductor. Additionally, coaxial cables include shielding, which is made of conductive materials to protect against electromagnetic interference and maintain the integrity of the transmitted signals.

The transformer, however, is not a component typically found in coaxial cables. While transformers are essential in various electrical and electronic applications for transferring electrical energy between circuits and modifying voltage levels, they are not intrinsic to the structure or function of coaxial cables. Coaxial cables primarily work through the transmission of signals along the core conductor and do not require a transformer to fulfill their intended role in communication systems. This distinction highlights why the absence of a transformer aligns with the standard architecture of coaxial cables.
