Direct Currents

Chapter

Abstract

We have seen that a conducting object tolerates no electric field in its interior as long as static equilibrium prevails. Suppose now that an electric field is nevertheless maintained there by some means. Then static equilibrium cannot exist; some motion of charge will occur. For example, a copper wire connected across the terminals of a battery does indeed have an electric field in it. Conduction electrons then flow along the wire, amounting to an electric current.
