Electric Electric field Field Insulator

AI Thread Summary

Insulation on a wire does not inhibit the electric field created by the current flowing through it. The strength of the electric field inside a looped wire remains unchanged regardless of insulation. Insulation primarily serves to prevent current leakage and protect against electrical hazards, rather than affecting the electric field itself. The external electric field is determined by the current and configuration of the wire, not by its insulation. Therefore, insulation does not impact the strength of the electric field inside the loop.

Imagine an electric field created by a electricity running through a looped wire. Leaving all other variables exactly the same, would the strength of the electric field inside the loop be less if the wire is insulated?

Thanks!

No. Why do you suspect insulation on a wire would affect the external electric field?

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
