Does electric current have any effect from gravity?

You can apply Newton's law to calculate the force of gravity on an electron which is say in a current carrying conductor flowing in the "up" direction. Simultaneously you can calucate the electric force on the electron due to the electric field in the wire. read more

Current flows in a closed loop. So any current moving “up” a wire (say to operate a motor on the roof) has a corresponding current moving back down towards the source. If there is a gravitational effect “slowing” the current moving up, there must be corresponding gravitational effect of speeding up the current moving down. read more

In some sense, gravity must effect electrons, because they have mass. But in reality, the effect of the gravitational force will be insignificant due to the much larger effect of their electrical forces. This is because the gravitational constant, 6.67300 × 10-11, is so small compared with Coulomb's constant, 8.987 x 10 9. read more

Electrons have a mass of 1/1836 of a proton or neutron's mass and any mass is affected by gravity. However gravity is the weakest of the four fundamental forces of the universe and is dominated easily by electrostatic attraction at such a small scale. read more
