Question

When a pnp transistor is operating in active region the current in n region is due to

Answer 1

Answer:

Explanation:

bipolar transistor have four distinct regions of operation defined by bjt junction biases the base_emitter junction is forward biasesd and the base_ collector junction is reverse biased.

The pnp transistor has three terminals: producer, base and gatherer. The producer terminal is associated with the left side p-type layer. The authority terminal is associated with the correct side p-type layer. The base terminal is associated with the n-type layer.  

The pnp transistor has two p-n intersections. One intersection is framed between the producer and the base. This intersection is called producer base intersection or producer intersection. The other intersection is shaped between the base and the authority. This intersection is called gatherer base intersection or authority intersection.  

Unbiased p-n-p transistor :

At the point when no voltage is connected to a pnp transistor, it is said to be an unprejudiced pnp transistor. At the left side p-locale (producer) and right side p-district (authority), gaps are the larger part transporters and free electrons are the minority bearers though in n-area (base), free electrons are the lion's share bearers and openings are the minority transporters.  

Biased p-n-p transistor :

At the point when outer voltage is connected to a pnp transistor, it is said to be a one-sided pnp transistor. Contingent upon the extremity of the connected voltage, the pnp transistor can be worked in three modes: dynamic mode, cutoff mode and immersion mode.
