What is another word for p-n-p transistor?
Pronunciation: [pˈiːˈɛnpˈiː tɹanzˈɪstə] (IPA) 
A P-N-P transistor is a type of bipolar junction transistor that consists of a p-type base region sandwiched between two n-type layers of semiconductor material - the emitter and collector. The functioning of such transistors involves the flow of electron holes, which are positively charged vacancies in their valence band, across the base region. Synonyms for P-N-P transistor are bipolar transistor, BJTs (bipolar junction transistors), and current control transistors. These terms are often used interchangeably to refer to transistors that regulate the flow of current in electronic circuits. BJTs are widely used in a variety of applications such as amplifiers, switch circuits, oscillators, and voltage regulators.
