What will happen when photon passing through high charged field?

I can't find my answer elsewere in internet.

 

What will happen when photon passing through highly positive or negatively charged field or high voltage medium? I remember I seen it somewhere.

Nothing will happen. The photon will continue on its way, as if the field wasn't there.

Photons can interact with electric charges, e.g. a photon can kick an electron or another charged particle out of its position. I can´t picture a "high voltage medium" so I don´t know about the 2nd part.
