本文通过对霍尔电压形成原因的分析与计算,指出霍尔电压的正负与导体载流子的正负有关,进而得出正负电荷沿相反方向运动形成的电流在霍尔效应中并不等效,即使同样的电流,只要载流子不同,则霍尔电压将会不同.其次,具体讲解和分析了不同载流子情形下霍尔效应在高考题中的运用.
In this paper, the cause of Hall voltage is analyzed and calculated. It is pointed out that the positive and negative of Hall voltage are related to the positive and negative of conductor carrier. And then it is concluded that the positive and negative charges move in the opposite direction, Equivalent, even if the same current, as long as the different carriers, the Hall voltage will be different.Secondly, the specific explanation and analysis of different carrier case Hall effect in the college entrance examination test.
