The voltage-ampere relationship of a two-terminal element is completely determined by itself, and there is no relationship with the external circuit which it is connected to. If you think this statement is right, choose T(true),or choose F (false). Choose A or B. 一个二端元件的伏安关系完全是由它本身所确定的,与它所接的外电路毫无关系。 [ ]
