Conductors in electrostatic equilibrium 1. The electric field inside a conductor is zero in electrostatic equilibrium . 2. Any net charge on an isolated conductor resides on its surface . 3. The electric field just outside the conductor is perpendicular to its surface. and has a magnitude equal to ⌠/∑ o , where is the local surface charge density . 4. On an irregularly shaped conductor, , and hence E just outside, is greatest where the radius of curvature is smallest 5. Every point on the surface of a conductor in electrostatic equilibrium is at the same potential – the surface is an equipotential.

Unformatted text preview: Conductors vs. Insulator Difference 1. Conductors conduct electrical current very easily because of their free electrons. 2. Insulators oppose electrical current and make poor conductors. 3. Some common conductors are copper, aluminum, gold, and silver. 4. Some common insulators are glass, air, plastic, rubber, and wood. Conductor: Electrons are held loosely Charge immediately spreads over entire surface. Insulators: Electrons are tightly bound No tendency for electrons to move into other areas...
