Is active is a cutoff region of transistor?
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
What is cutoff region in transistor?
The cutoff region is when the transistor doesn't have sufficient base current to drive a larger current from emitter to collector. Therefore, the transistor does not turn on and stays shut off.
Why collector is made larger than base and emitter in a transistor?
Collector has larger area than base and emitter because base collector is reverse biased, hence the current flow here due to the minority carriers and the large power dissipation takes place by the majority carriers, this power dissipated in the form of heat.. To cool the device from heat we made the larger area........
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.

What is the voltage across collector to emitter when transistor is in cut off region?
In the cut-off region of a transistor, the base-emitter junction is not forward-biased, meaning the transistor is effectively turned off. As a result, no current flows from collector to emitter, and the voltage across the collector to emitter (V_CE) is approximately equal to the supply voltage (V_CC) connected to the collector. Therefore, V_CE is at its maximum value, close to V_CC, indicating that the transistor is not conducting.
Why a transistor can be operated in active region?
a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
What is breakdown region?
The breakdown region of a transistor is the region where the supply voltage, Vcc, becomes so large that the collector-emitter junction of the transistor breaks down and conducts, even though there is no base current.
How many region a transistor have?
A transistor typically has three regions: the emitter, the base, and the collector. In a bipolar junction transistor (BJT), these regions are crucial for its operation, with the emitter injecting charge carriers, the base controlling their flow, and the collector collecting them. In a field-effect transistor (FET), the three regions consist of the source, gate, and drain. Each region plays a vital role in the transistor's functionality and performance.
What is meant by saturation region active region and cut off region?
In the context of a bipolar junction transistor (BJT), the saturation region refers to the state where both the base-emitter and base-collector junctions are forward-biased, allowing maximum current to flow from collector to emitter. The active region occurs when the base-emitter junction is forward-biased while the base-collector junction is reverse-biased, enabling the transistor to amplify signals. The cutoff region is when both junctions are reverse-biased, resulting in minimal current flow, effectively turning the transistor off. These regions define the operational modes of the transistor in electronic circuits.
Which is the largest of three transistor current?
Emitter current is the sum of collector current & base current , hence the largest. Base current is the smallest.
