    Reflexionar e investigar

    1. Explique cómo la capacitancia puede aumentar cuando se utiliza un material dieléctrico.
    2. Explica cómo funciona un anillo corona.
    3. ¿Qué formas de electrodos son las más comunes? ¿Por qué?

    Para probar en casa

    1. Intenta liberar una descarga estática de tu dedo a algún objeto metálico. Mida la distancia entre el dedo y el objeto metálico al momento de la descarga. Conociendo el voltaje de ruptura del aire, ¿cuál era la diferencia de potencial entre tu dedo y el objeto metálico justo antes de la descarga?

    Para probar en el laboratorio

    1. Proponer un experimento para medir el punto en el que diversas sustancias experimentan avería eléctrica.
    2. Proponer un experimento para medir la constante de permitividad de vacío (\(\epsilon_0\)).)
