RESUMEN

En este trabajo consideramos una capa resistiva cilíndrica que transporta una corriente constante. Una batería genera la corriente en el centro del conductor. Estudiamos el comportamiento del potencial, campo eléctrico y cargas superficiales cerca de la batería.

Palabras claves: Potencial eléctrico, potencial cerca de la batería, cargas superficiales.

ABSTRACT

In this work we consider a long, resistive cylindrical shell carrying a steady current. A battery in the middle of the wire generates the current. We study the behavior of the potential, electric field and surface charges close to the battery.

Keywords: Electric potential, potential close to the battery, surface charges.
