Sorry for my obvious question, but I am not from the field of electronics and electric engineering.
I was reading this article: The first sentence in the introduction says: " All solid dielectrics exhibit the propensity to accumulate electrical charges under electrical stress beyond an electric field threshold. "
First question, is dielectric polarization the same as saying dielectric accumulate electric charges ?
I would like also to ask about the diadvantages of accumulation of electric charges in dielectrics, can some one give a me a real example from daily life problems?
I read somewhere that this can cause cables to be damaged, how this occurs?
Thank you in advance.
