Which is the largest current in a pnp transistor?
emitter current
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.
What leg of a bipolar transistor carries the largest current?
The middle one, it has extra beef in it's wiring. Hopefully that helped.
What percentage of the total current in a transistor flows through the collector?
The total current in a transistor is the emitter current, which is the sum of the collector current and the base current. The ratio of collector current over base current, in linear mode, is beta-DC, or hFe. However, in order for linear mode to be true, the ratings of the transistor must not be exceeded, and the collector current must not be limited by the circuit. Note also that hFe is temperature dependent, and is expressed in the data sheet as a minimum, not an absolute value - it can vary from transistor to transistor.
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.
Which is the largest current in a pnp transistor?
emitter current
How many states does a transistor have?
A transistor can be in three conditions or states. It can be active (at a voltage higher than the emitter), in saturation or cut off (no current).

What is the difference between a switching transistor and an ordinary transistor?
In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...
What happens when the base current of a transistor is decrease?
in a properly biased transistor, collector and emitter current also decrease
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
What is meant by saying at what current is transistor biased?
The saying "at what current is transistor biased" means to ask the current through the transistor when there is no signal present. Typically, a transistor is biased at the center of its linear region, so as to minimize distortion. This, of course, depends on whether or not the transistor is AC or DC coupled, and where the clipping points might be.
How is current amplified in a transistor?
Transistor increase the strength of a weak signal from the base

Difference between bjt and ujt?
UJT is the voltage controlled device.in which only one mejority carriers are responsible for current flowing. UJT is one junction transistor and it is three terminal emitter and two base. BJT is the current controlled device. in which both mejority and minority carrier are responsiblefor current flowing. this type of transistor consists of two junction and three terminal these are : emitter , base , collector.
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.
