## Transistors

Transistors Definition: A transistor consists of two PN junctions formed by sandwiching either p-type or n-type semiconductors between a pair of opposite types. There are two types of transistors: n-p-n transistor p-n-p transistor An n-p-n transistor is composed of two n-type semiconductors separated by a thin section of p-type in fig (i).A p-n-p transistor is … Read more
