常見例句雙語例句Consequently, no load current flows through R6 because Q2, whose base-emitter voltage is now 0V, has turned off.由于Q2的基極-發(fā)射極的電壓為0V而截止，因此沒有負載電流流過R6。www.c-cnc.comWhen choosing a value for R6, ensure that Q2's base-emitter voltage is less than approximately 0.5V at the maximum permissible value of the load current.選擇R6的阻值時要確保在負載電流的最高允許值的條件下，Q2的基極-發(fā)射極電壓大約低于0.5V。www.c-cnc.comIn the event of an overload when ILOAD exceeds its maximum permissible value, the increase in voltage across R6 results in sufficient base-emitter voltage to turn on Q2.當ILOAD超過最大允許值時發(fā)生過載情況，R6上的電壓增大導致基極-發(fā)射極電壓足夠大到導通Q2。www.c-cnc.com 返回 base-emitter voltage
