Does gravity effect electricity?

Yes, because electrons have mass though it is tiny.

See above. Gravity does have an effect on electricity.
But it is the weakest of the fundamental forces. Electromagnetism easily trumps gravity in the physics of electricity. Otherwise, we would have to constantly tweak electrical systems with changes in gravity, like in space flight or high g airplane maneuvers.

About as much as a fart can affect the wind.

Of course.
Everything is affected by gravity, even massless particles like photons.

Eddington’s observations during a solar eclipse proved that the light from a star was bent by the mass of the Sun.

I must agree with @ARE_you_kidding_me .

Of course it does. It even affects light particles.
