If a BJT amplifier is operated as a switch that is off, this operating condition is known as________ A) thermal runaway B) V_P C) cutoff D) saturation

Question

Quizplus · Accepted Answer

When a BJT amplifier is operated as a switch that is off, it is in the cutoff region where there is no base current and thus no collector current flows. Option A, thermal runaway, is not applicable in this scenario and option B, V_P, is unclear and not a valid option. Option D, saturation, is the opposite operating condition where the transistor is fully turned on and cannot be used as a switch that is off. Therefore, the correct answer is C - cutoff.
