Need help conceptualizing constant voltage in hollow sphere

[cmkluza]

I realize that this is probably really basic, but I can't quite conceptualize a hollow metal sphere having constant voltage and zero electric field inside of it. I've searched around on the Internet, and I've seen stuff about Gauss' Law, but even after reading into that a little bit I can't make sense of it.

Would anyone here be able to try and explain this to me or give me some intuition on it?

Thanks for any help!

The potential at each point inside the sphere will be same at every point. This is because of uniform charge distribution of the charge on the surface of the sphere. Hence, electric field will be zero inside the sphere. There is no 'gradient' of potential inside.
