Zorluk: OrtaTransistors

When a bipolar junction transistor operates in its cutoff region, the collector-to-emitter path behaves as an open switch, preventing significant current flow through the output circuit.

Cevap: Cevap

Cevap

True
In the cutoff region, the control junction receives negligible bias voltage, preventing base current from flowing. Consequently, the output conduction path between the collector and emitter remains non-conductive, functioning electrically like an open switch.

Adım Adım Çözüm

1
Identify the specified operating state of the transistor
The statement specifies operation in the cutoff region.
A transistor's conductivity between its output terminals depends directly on its operating state: cutoff, active, or saturation.
2
Evaluate the current conduction characteristics in cutoff
Without base drive voltage, base current is zero, which halts collector current and creates an open-circuit condition.
In electronic switching applications, cutoff represents the 'off' or open-switch state where current cannot pass to the load.
