zener current造句

例句与造句

1. Resistor, R1, supplies the Zener current and the base current ( ) of NPN transistor ( Q1 ).
2. Thus, as long as the Zener current ( ) is above a certain level ( called holding current ), the voltage across the Zener diode ( ) will be constant.
3. The regulation of this circuit is also not very good because the Zener current ( and hence the Zener voltage ) will vary depending on V _ \ mathrm { S } and inversely depending on the load current.
4. Once " R " 1 has been calculated, removing " R " 2 will allow the full load current ( plus the Zener current ) through the diode and may exceed the diode's maximum current rating, thereby damaging it.
5. It's difficult to find zener current in a sentence. 用zener current造句挺难的
