However in very poor conductors at sufficiently high frequencies, the factor on the right increases.

Pure water is a rather poor conductor of electricity.

The plastic, a poor conductor, sticks until the charge is canceled.

Even solid ice is a rather poor conductor of heat.

Heat flow is frustrated because the adjacent areas are separated by a poor conductor.

If charge collects on a poor conductor, it cannot move.

So we can imagine that pure ice having no charge carriers would also be a poor conductor.

They are also thought to be poor conductors of electricity and heat.

Scale reduces flow through pipes and is a poor conductor of heat.

This lightweight carbon structure is a poor conductor of heat.
