Definition: Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric …
WebApr 28, 2014 · The electric field balances out the radially inward attraction between electrons due to the current flow. There is a compensating positive surface charge density $\sigma = (R / 2) \beta^2 \gamma^2 \rho_0$ around the surface of the wire which balances out the negative bulk volume charge, so the radial electric field vanishes outside the wire.
