【单选题】We define : V D is the voltagebetween P terminal and N terminal, ID is the current passing through the diode,and it’s direction is from P to N. if >0 and>0, the diode is in the ( ) region
【单选题】Most modern diodes are based on semiconductor ( ). In a p-n diode, conventional current can flow from the ( ) side (the anode) to the ( ) side (the cathode), but cannot flow in the ( ) direction. ( )
【单选题】We define : V D is the voltagebetween P terminal and N terminal, is the current passing through the diode,and it’s direction is from P to N. if the diode is in the reverse-bias region,then ( )
A.
>0, >0
B.
=0, =0
C.
< 0,=- , isreverse saturation current of the diode
