B Breakdown Potential

  1. Mar 28, 2016 #1
    I want to know, for a given parallel plates capacitor, the breakdown potential equals to
    Vmax=Emax × d or Vmax=Emax/d
    Where d is the distance between the plates of the capacitor

    In addition to cnh1995's answer, you can use dimensional analysis to help you remember the answer. Just remember that the units of Electric Field are Volts per meter. :smile:
