When a BJT has its base-emitter junction reverse biased and its collector-base junction reverse biased, it is in the （ ）.
举一反三
- If a BJT is applied in the cutoff region, the base-emitter junction must be ( ) biased and the base-collector junction must be ( ) biased
- When a BJT is biased in the cutoff region the collector-to-emitter voltage is typically equal to （ ）. A: the emitter voltage B: the collector supply voltage C: 0.03 V D: the collector current times the collector resistor
- β is the ratio of _____. A: collector current to emitter current B: base current to collector current C: collector current to base current D: emitter current to collector current
- When a BJT is operating in the active region, the voltage drop from the base to the emitter VBE is approximately equal to the____ A: base bias voltage B: base current times the base resistor C: diode drop (about 0.7 V) D: emitter voltage
- When reverse -biased, an ideal( ) would block all current. Areal one lets perhaps 10 microamperes through- not a lot, but still not perfect.
